This is going to play out like 2016. The Left are to make every little thing. He does into the biggest baddest thing of all time. The world didn't end in 2016, so why will it end now?
No one is expecting "world to end". It's just going to get somewhat shittier whereas it could have gotten better or at least stayed the same. Also for some minorities it's going to get a lot shittier.
There's indication Netanyahu wants to seize parts of Gaza into Israel. If it comes to that, there is no way Trump is going to do anything about it (except try to extract maximal gain for himself in terms of favors etc.)
I really, REALLY hate throwing "both sides" out there because it's usually bullshit. But I don't think there's a chance in hell that any of the candidates would stop Israel from doing that. There's barely a slim chance that either of the Dem nominees would have even done a damn thing more than lip service.
I can't really say you're wrong, since we will never know. I had the feeling that Biden was reluctant to do anything because of the incoming elections, whereas Harris might have done something. But alas, we'll never know.
(as a side note, I feel like you'd have gotten away with both parties better here, as the "both sides" is typically just used to equate nazis with regular people and normalize/excuse their behavior - nothing wrong with hating the term)
Honestly I do expect this term to be worse than the first. He had to temper his behavior and choices because he wanted to be reflected. Now there isn't any chance of reelection so he will be more likely to do drastic things with no regard for the consequences.
Historically that's not necessarily the case. Authoritarians who come to power via somewhat democratic means in their first terms to be much more mild relative to subsequent terms where they solidify their hold on institutions.
One notable example would be Putin's first term (which is largely seen to be a fair win) or even when Medvedev was ordered to warm the seat. It always only gets worse, at least from historical examples.
The bigger question is whether the US opposition has any willingness to fight, which I don't believe to be the case.
