20-30 years ago Europe was worth saving, and defending. Now, I don't think it's worth the life of "one Pomeranian Grenadier". Yes, Poland and Baltics seem to really like us (for now), simply because Big Bad Putin is sitting on their doorstep. Kinda like how Brezenhev was sitting on (West) Germany's doorstep during the Cold War. Everyone wants to be our bestest buddy when the wolf is at the door, but we can just *expletive deleted*ck-off when the threat goes away. And *expletive deleted*ck us over on trade in the mean-time.
I'm tried of spending American blood and treasure defending ungrateful Euro-trash, especially when they aren't willing to foot the bill. So yeah, if Poland and the Baltics are willing to pay (and by "pay", I mean the cost of payroll, equipment, maintenance, R&D, and infastructure), then fine. I'm good with us being a mercenary Army. At least it will be at no net cost to the US Taxpayer.
