could be that planes would be moved if most planes on russia's western flank bases were junked.
it is likely some western bases would be more difficult to attack.

but these 2 distant bases have long existed solely to deploy against america, and it was an intentional message partly to trump.
first level thinking had me wonder why help trump, who not only backs putin with words and attempts to reduce sanctions, but who actually cutoff supplies and intelligence support, thus triggering greater battleline aggression against ukraine.

- ukraine was deemed weak and cardless by trump, but can flex. they just accomplished something america has never been able to accomplish in decades of cold\proxy wars, despite the specific threat profile to america.

- ukraine has encountered enough american political and military staff that would realize the unique impact and value of this strike, not for themselves, but for america's benefit. they are gambling that growing this kind of support with real action can counter the unholy trump\MAGA\putin alliance.

i am much more optimistic about the latter point, as trump is less impressed without his personal benefit.
