He was also calling for the other NATO nations to spend more for their defense, which served as a deterrent. Why did they have to wait until an attack on Ukraine to see he was right?
If we had followed that policy instead of electing (I know) Biden, he might have been able to negotiate an agreement.
As for his policies, I did a search. To no surprise, all attacked him, but for all kinds of different reasons that in many cases contradicted each other. The only thing that was consistent was their hostility towards Trump.
Trump wants Ukraine to receive jets.
I would agree the attack on Ukraine was wrong, but I don't know who to believe on what, so I can't say if that would be the wrong or right move.
Trump was telling the rest of our NATO alliance to build up, while he was strengthening our own military against the Russians.
Biden has been blocking the jets that Trump wanted Ukraine to have.
