This is false. The west helps because it wants to. The west helps because "israel" acts as a military garrison and outpost to project power across the middle east for them (specifically the US who having totally fucked Europe in trade deals and on many other issues shows themselves to be the master of the entire west). The west helps because they want to help white looking people genocide and colonize brown people because they've done so themselves for centuries and fully believe the "savage natives" narrative against the "civilized Europeans". The west helps because Europe can pretend its holocaust guilt. The west helps because deep down many want all the Jews over there and not back in Europe because they are antisemitic. The west helps because "israel" ran Jeffery Epstein and probably other pedophile networks to get blackmail material on elites in the west.
The west does not help because they have nukes. The west allowed them to get those nukes. They were "stolen" from the US, the material to start their breeder reactors along with critical knowledge. The US could if it wishes take out "israel" using maximum force but it is useful to the US so it not only lives it is propped up and given bipartisan support while suppression of speech of those against it occurs.
Do NOT reverse the roles here. The west created "israel", they watched idly as it conducted its genocide before it ever had nukes, they supported it, they justified it, they blamed the Palestinian victims. The west is not some victim of extortion here, it created this monster, it supported it, even now without it the entity would collapses.
