On the Ukraine thing: Putin knows the art of the deal, so he'll likely demand all of Ukraine, knowing perfectly well he won't get it, and will instead keep Crimea and gain the four eastern oblasts that allegedly voted to become part of Russia two years ago.

Despite Dugin's claim that the continued existence of a Ukrainian State is a threat to Russia The Neo-Muscovy Empire, even the outcome I predict is a huge strategic advantage (martially, industrially, and commercially) for Russia. The caterwauling from the usual suspects will get worse. If it seems quieter, that's only because they aren't being broadcast as widely.
On the Israel thing: rabid anti-Semites call him "Zion Don" for a reason. Worst case scenario, he lets Yahoo become a dictator, the Israeli government stages false-flag attacks its own people in various border areas (as was allegedly the case on Yom Kippur), uses this as justification to invade every surrounding nation and gain huge amounts of territory just as it did during the Six-Day War, and we get stuck with the bill. However bad you think the worst case scenario is, you've seen nothing unless you spend time lurking in JQ circles as I do.
On the pardon thing: the reason Trump didn't pardon Assange and Snowden the first time round was because Mitch McConnell, swamp creature that he is, threatened removal from office during the first impeachment hearing. Worst case scenario is that Trump is even more hamstrung by the swamp during his second term.
More broadly speaking, I don't know how much you pay attention to the internal politics of the Libertarian Party, but they shot themselves in the head before even running Chase Oliver. The LPUSA keeps finding new and inventive ways to make itself utterly irrelevant. Libertarians who insist on remaining loyal to the Party are fools, as it is far more feasible to reform the GOP, join the National Futurists, or make a new party altogether.
