When the aim is genocide and the denial of the right of the Palestinians to their own state, Israel will gradually lose the support of even its erstwhile most staunch allies like the US and many European nations. Simply because these governments have to answer to their own people why they're spending billions of dollars of taxpayers' money to support a genocidal campaign with no clear objectives except to shore up Netanyahu's moribund political fortunes by winning the support of Zionist extremists.
The day the US stops supplying arms and money is the day the Zionist state will be annihilated.
