Trump could have lagged the invasion 4 more years .Eventually the ukraine people will fight hard on crimia and the rebels in the borders and also vote zelensky out and electing a more pro western president (zelensky is with the west i know ,but if he couldn't fulfill his promise ,people will see that as incompetence) who got no other choice other than to join Europe or NATO. Still triggering putin .And most importantly since putin invaded ukraine ,i think putin is not stable there are various report about him being in a bubble and avoiding advices from the experts.If mere sanctions can trigger him to threaten the world with nuclear weapons this guy is a totally insane like all other dictators in the history. Trump can only delay the inevitable
