Tucker has always been put resources in America and not overseas type guy. Not exactly isolationist but definitely a minimalist wrt foreign entanglements sort of guy. That Democrats try to claim he is a "Russia asset" is just one of their more retarded talking points. An extension of their half decade long Russia, Russia, Russia nonsense.
Now, I think we do have to do everything we can to make sure Russia loses in their war of aggression because Putin will continue on if he is able to do so. Putin said as much in his invasion day speech. If we make Ukraine sign a Minsk 3 agreement then it will be a failure, Putin will just ignore it like he did the previous two, and he will just rearm and rebuild before having a third go in a few years. So the only real way to stop this is to give Ukraine everything we can do they can actually push Putin's forces completely out of Ukraine. Only then will Putin not be able to deny that he lost.
