It wasn’t, but that time America was not an active participant in the game. They were amongst those trying to provide aid to Gaza (or atleast that was the official stance).

WTF? They built a pier off the shore of Gaza that lasted less than a week and airdropped a few crates of food. This is entirely outweighed by the unconditional support of the Israeli government's genocide. They provided everything Israel ever wanted and never made an actual ultimatum to Netanyahu's government. They absolutely were active participants (in fact, the main instigators).

The abhorrent behaviour of Trump government is a radically opposite stand. Concentrating the people at aid centers, by taking advantage of their hunger, and then nake them sitting ducks.

This did get a lot of media coverage in early 2025 but AFAIK it's not exactly unprecedented and Israel had already been doing similar things in the early stages of the operation post Oct 7th. At the very least, it's hard to say whether these tactics, as cruel and horrifying as they are, were any more lethal than what they were already doing for a year before that.
