President Biden built a global coalition to help Ukraine defeat Russia.
Of course no. There is no possible coalition able to defeat Russia and achieve declared European goals.
Trump is ready to give Putin everything he wants
Oh, no. I'm pretty sure he is not ready return Alaska and California to Russia (and even ready to use nukes to defend them), as well as Russia is not ready to give up Crimea and Novorussia. (Both prefer to use nukes rather than allow another side take those positions).
Russia wants to take Alaska and California, but not ready to pay even one million of Russians to take it back. The USA want to take Crimea and Novorussia but they don't want to pay even one million American lives for that. Russians want to keep NATO out of Ukraine and ready, if necessary, to pay more than 10 mln to ensafe it, and ready to pay any amount of lives (even 90% of population) to prevent "decolonisation of Russia".
Americans wants to keep Alaska and California in the USA (or, at least out of Shanghai block) and ready to pay even 10 mln lives to ensafe them. Americans, I believe, ready to pay any amount of lives (even 90% of their population) to prevent "decolonisation of America".
Both sides know it, both sides are good. Biden also knew that America isn't ready to raise bets to the level of nuclear war, and, therefore, America can't "defeat Russia" and force Russians leave Ukraine as well as Russians can't force Americans to leave California.
Biden's goal wasn't to win the war. He knew that it is impossible. His goal was just to steal some American taxpayers money (and, may be, after defeat of Ukraine just to get some Ukrainian refugees/militants to use them inside America).
