The alternative is what the last five American presidents have done: containment. There's a reason Biden, Obama, Bush, Clinton and Bush didn't start the war that Trump did. This is why.
Trump could EASILY increase US support to Ukraine. He could have even done what France was flirting with, which was deploying boots on the ground in defensive positions as a "red line". Bringing up Ukraine/Russia is not in good faith. You know this, you know that democrats have called for aggressively arming Ukraine and never wanted this dumb Iran war.
Trump isn't "strong" until he actually calls Putin's bluff on nuclear weapons. You're not gonna do it Putin, and I'm fully willing for me and everyone I know to die in WW3/nuclear holocaust just to make sure Putin goes to hell a bit faster.
Trump indeed has. And that chart doesn't show Miram Adelson's $100M given to Trump's campaign plus whatever she and her husband gave before the first term, so even terms of money Trump is far ahead. From a woman who describes herself as an Israeli stuck in America.
However, Biden is completely pro-Israel. He would do anything for them and has said so. Guessing he didn't think attacking Iran was the best thing for Israel. Well look at how it's going.
