Yes that could be used as an excuse BUT i think given Trumps comments and the WH's failure to even address them, the Govt should just say its no longer appropriate due to Trumps comments.
Enough of this pussy footing around, its not getting us anything at all.
It would also boost K. Starmers image too, instead of, as you say, Trump.
Trump and MAGA aren't going anywhere and we need to urgently move away from the USA, there is no point, Trump & his ilk will never come to our aid.
However, i was pleased to listen to a former US Marine Col (who served in Afghan) and ex Trump advisor absolutely demolish Trumps comments yesterday, a very moving tribute to NATO troops.
At least there are some decent Americans.
