Here is why Putin shows he is losing;
If Putin is losing, it is despite the big break he caught when Trump was elected, not because of it.
Trump has done nothing but undermine Ukraine's position since he got reelected. Conceding positions like Ukraine's NATO membership before negotiations even started. Halting weapon shipments and intel sharing. Trying to blackmail Ukraine into a exploitative minerals deal.
Trump started a trade war with Ukraine's supporters, yet refused to implement sanctions against Russia.
Even now, while Ukraine is being hit daily by Russian drones and missiles, he still drags his feet on supplying Ukraine with air defence systems even when other countries are offering to pay for them.
Yeah I am sure, this man would have bombed Moscow on Ukraine's behalf... .
