What would Trump do differently if he was not a Russian agent?
Trump is not a Russian agent, he is too stupid for that. Instead of using weapons and monetary support as leverage towards Ukraine to favor Russia, he has voluntarily given it up during 2025 and then US negotiators are surprised that it is hard to force Ukraine to do anything because there is no leverage towards Ukraine.
On the other hand EU has massive leverage on Ukraine because they are effectively keeping them fighting, but Russia won't even engage with EU for whatever reason, instead they are negotiating with USA to get a deal, which can't be enforced because USA lost leverage long time ago.
