Ukraine still retains the ability to militarily defeat Russia but the west has been a day late and a dollar short.

I think that may have been the case at one point, but if you look up Ukraine and prosthetics, and compare to the population and military strength you'll see that it's more than a day late at this point. Even if you're of the opinion that deaths aren't that high, prostheses need paints a grim picture for the future of that conflict. Countries like France were trying to negotiate settlements and ceasefires earlier in the war but the US kept blocking them and hinging financial and military support on not negotiating, which is how we got where we are there.

The residents of Gaza choose this by choosing Hamas as their government and starting a war with Israel. Iran is similarly responsible.

First, I disagree. Hamas was elected decades ago and there have been no elections since, and more than 50% of Gaza was children before Oct 7th. The majority of people who live in Gaza did not elect Hamas.

Secondly, even if this was the case, what were Gazans going to do about their situation, protest? Israel controls and controlled flow of trade (via a blockade), water, and electricity into Gaza before this conflict. A huge percentage of the Gaza population had injuries from IDF soldiers deliberately shooting them in the kneecaps from earlier protests or getting too close to the fences they erected. On top of that, Israel helped fund Hamas and got them into power, so Oct 7 was just Israel reaping what it sowed. Gaza was an open air prison hosting a slow genocide before this conflict, all that's happened now is Israel moving up the timetable.
