Ukraine is NOT in NATO
Croatia has no treaty obligation to defend them.
Maybe they could be like France and send 50 soldiers to Romania
I understand that perfectly well, no one expects them to put their entire military on the front lines if a war were to break out, but open say if fighting starts they are going home is not being a good partner in NATO.
Whatever capabilities they have they could be put to good use.
I don’t want war under any circumstance, but I’m not naive enough to believe a war couldn’t break out, given how Biden has been wrong on just about every foreign policy issue in the USA for the last 40 years, I have no confidence Biden is going to get this situation handled correctly, but a war is much more likely if NATO members start running home before anything really happens.
