Is Ukraine about to have a war?

[tartare]

I'm trying to work out how the Ukrainians get their `new' MiGs over the border from Poland without being shot down.
I assume they'll have to move quick smart.
EDIT: Ignore that - I see the plan to supply old MiGs from Poland and Slovakia is now a nonstarter.

Presumably defending the west of the Ukraine becomes an absolute imperative if you're going to continue to ensure the continued NATO supply of NLAWS and other weapons and materiel flowing into the country?
As Russia moves west - if they push right to Lviv the situation on the border must be likely to get very fluid - high risk of a Poland/Hungary/Romania v Russia incident or shootdown.
Could happen as much by mistake as anything.
