The lobbyists for the military/industrial complex are numerous and exceedingly well-paid.

Which is how and why campaign contributions have become a systemic evil - it chains the platforms of politicians to the desires of the wealthy and powerful, thereby eliminating any ability for politicians to “do the morally/ethically correct thing”.
Most of the western world was philosophically “on Israel’s side” because of the unrelenting evil of Hamas -- Hamas does’t care if every single Palestinian dies, so long as they “win”. Plus, genocide of the entire Israeli population has been baked into Hamas’ DNA from the beginning. But with this war, Israel has gone all “hold my beer and watch this”, and is making a legitimately successful bid at becoming the materially greater evil.
It’s an ESH situation, with the Palestinian people caught in the crossfire.
