President Trump is a very creative thinker more patient and strategic then probably most give him credit for. His push to end the war Russia started has shown him to be man seeking peace. His bombing iran shows he will also mess you up. I think he starts going after anything that produces income for putin. Hence trying to get the price of oil down and removing Venezuela from the Russian side of the ledger. India probably about to get a lot of h1b holders back.
Trump has realized that the EU and Zelensky have been sabotaging his latest efforts at peace agreement.
Sanctions are already on Russia and so far they have not been successful.
