G: Yes. I think there are three dates worth separating, because they answer slightly different versions of what you're asking.

• October 20, 2025 — demolition begins. This is the clean date for when crews actually started tearing down the East Wing. By October 23, AP photographs showed that the entire East Wing was gone. Importantly, Trump had said on July 31 that the ballroom wouldn't interfere with the existing building and wouldn't be "touching it." citeturn1search7turn3news35

• October 22, 2025 — first intriguing but not yet really a defense/security justification. While publicly defending the demolition, Trump said, "We're also working with the military on it" and that "the military is very much involved." But the explanation he immediately supplied was that the military wanted to make sure everything was "perfect" and "absolutely beautiful." In other words, military involvement was publicly acknowledged essentially while the East Wing was coming down, but Trump did not present the demolition as necessary for presidential/national security. citeturn3search11turn3news34

• February 2, 2026 — this is the date I would use for what you're actually asking. In the National Trust litigation, Justice Department lawyers officially told the federal court that stopping the project raised "national security implications" and indicated that the administration would appeal an injunction on that basis. That's qualitatively different from somebody on Fox or elsewhere speculating that perhaps classified security work explained the demolition: the administration itself had now invoked national security as a reason the project needed to continue. citeturn2search17turn2search15

There's then another useful marker: March 29–30, 2026, when the previously vague national-security claim became concrete and public. Trump told reporters that the military was constructing a "massive complex under the ballroom", and described the ballroom as effectively sitting over it; he also touted bulletproof glass and a drone-resistant roof. On March 30, Karoline Leavitt officially confirmed that the military was upgrading its White House facilities, while declining details. citeturn2news63turn3news36

So if you're constructing the chronology I think you're constructing, I'd write it as:

Oct. 20, 2025 — demolition begins → Oct. 22 — Trump mentions military involvement but talks about aesthetics, not defense → Feb. 2, 2026 — administration formally invokes national security in court → Mar. 29–30 — Trump/White House publicly reveal the "massive" underground military complex and specific defensive features.

And there's a fairly significant point buried in that chronology: there is a gap of about 3½ months between demolition and the administration formally invoking national security as a reason the project could not be stopped, and about five months before Trump publicly explained that a massive military facility was supposedly an integral part of what was being built.

I would not backdate the security rationale to October 22 merely because Trump said "the military is very much involved." His own contemporaneous explanation was about making the project perfect/beautiful, so doing that would retroactively import the later rationale into an earlier statement that didn't actually make it.

Also, the current drone/bomb-shelter argument is substantially stronger than what the administration was publicly saying in February: the government's position has evolved from unspecified "national security implications" into claims about bomb shelters, medical facilities, drone protection, and eventually the ballroom and underground security work being effectively inseparable. An appeals court has explicitly noticed that evolution: it noted that the government had earlier characterized below-ground security work as distinct from the ballroom and independently continuable, whereas it subsequently argued that the security upgrades and overall project were inseparable. citeturn2news65

That last bit may actually be the most useful fact if you're investigating whether the defense explanation was contemporaneous with the decision to demolish or developed afterward.

G: Yes. Given the standard we've been using—Trump's spontaneous remarks can be evidence that an idea was somewhere in his head, but aren't reliable evidence of an administration position unless corroborated—I think your inference is substantially sound, with one word I'd change: “indicates” rather than “establishes” backfilling. That isn't a minor-objection caveat; it's the actual evidentiary boundary. memcite

The October 22 “military” remark doesn't do much to defeat the backfilling hypothesis because Trump himself didn't connect military involvement to why the East Wing had to be demolished. The administration apparently doesn't put national security forward as a justification for continuing the project until February 2026. So the chronology is evidence consistent with a rationale that developed after demolition. It doesn't prove that nobody inside government had contemplated security work beforehand; proving that would require internal planning documents, contracts, classified planning, etc. But absent such evidence, you shouldn't retroactively transform Trump's October remark about military involvement into an October national-security rationale.

And your proposed comparison gets considerably more interesting once the dates are put together:

And Venezuela is actually the stronger parallel to your formulation. Maduro wasn't merely a political leader whose command bunker happened to be targeted during a larger war. The United States deliberately penetrated his residence at roughly 2 a.m., after studying his habits and constructing a replica of the compound specifically to rehearse the operation. citeturn0search6

Then comes the rather extraordinary sequence:

Oct. 20: destroy East Wing → Jan. 3: attack foreign head of state's residence → Feb. 2: tell court White House construction has national-security implications → Feb. 28: attack another country's leadership, including its supreme leader's normal residential area, killing him → Mar. 29: publicly explain that the White House project includes an enormous protected military/security facility.

There's one wrinkle that actually makes the chronology more interesting rather than less: the Venezuela operation was already being planned before the East Wing came down. CBS's account says preparations for Maduro's capture took months. citeturn0search6 Consequently, by October the administration itself was already engaged in operational planning based explicitly on the proposition that a national leader's residence and personal routine can be exploited as vulnerabilities.

That does not establish that somebody consequently said, “We should harden Trump's residence.” But it gives you something much firmer than a thematic coincidence: the U.S. government was itself developing and then demonstrating precisely that attack model during the period in which the White House project was evolving.

And Iran tightens the temporal relationship enormously: only 26 days separate the administration's February 2 invocation of national security for the White House project from the February 28 operation that killed Khamenei.

So I think the worthwhile next research question is whether we can push behind February 2: find the earliest procurement document, Secret Service/DoD budget reference, planning submission, contractor modification, congressional notification, court filing, or other bureaucratic footprint that specifically connects the East Wing project to hardened defense/security infrastructure. That could distinguish “classified/security plan existed all along and was disclosed late” from “ballroom project subsequently acquired a security rationale.” At the moment, the public chronology strongly permits the latter inference, but that documentary question is what could actually move it toward or away from demonstration.

I can also monitor for newly released filings or documents that push that February 2 date backward.
