Definitely possible, at this point it's all speculation anyway.
I simply hope that if they do, I am out of the conscription age when it happens.

And for all that Europe only recently started rearming, with every month that goes by the European level of war preparation grows higher, and while I doubt Europe could hold Denmark, at this point the yanks would definitely not have a particularly easy time trying to invade.

Also, If i remember correctly the french were willing to step in militarily last time the americans came demanding it.
