its just money, aipac either funds you or your opponent. these cowards just take the money and go on with their pimping for lobbyists while laughing at murdered children.

Israel is a close ally to Russia too, up until very recently. Netenyahus campaign was based more on his friendship with Putin than with Trump or Biden.

This is superficial. Neither Russia nor China are particularly antagonistic to Israel or the Gulf states, even if they see the US as a foe in their own region. Russia for example is very careful about balancing its relations with the Gulf, Israel and Iran. China, views Iran as a potential foothold to the region, but China actually benefits from the US presence, it is far more energy import dependent than the US and has no desire to fuel instability by helping Iran pursue offensive goals.

The actual reason that Iran and the USA are enemies has to do with the US' sectarian alignment with Sunni powers and Jewish nationalism, and more complicated reasons relating to politicial and religious struggles in the entire region that Iran happens to be one side of (i.e anti-monarchism, clericism, etc). And an institutional (and not necessarily rational) hatred of Iran in the US top brass due to its role in helping Iraqis and Lebanese fight American soldiers.

You cannot talk about this issue in terms of "Russia-China-Iran" balancing without mentioning the deeper and much more relevant issues that make US-Israel relationship exceptional on a globsl level: post-Holocaust philosemetism, anti-Islamism, anti-Arabism and (very underreported) Christian piety that actually motivates US-Israel policy. And the Israel lobby, which is so deeply engrained that Israel is treated more or less like the 51st state.

Politics goes far beyond amoral power calculus. You could have justified a ceasefire and even an embargo on Israeli arm transfers in accordance to amoral power calculus, but for Biden, Blinken and the rest, this is a moral question relating to a transcendent moral and religious cause, steeped in centuries of historical memory.

I have zero doubt that Joe Biden believes that by helping murderous racist Netanyahu slaughter and expel the people of Gaza, he has placed himself in the company of Cyrus the Great and other deliverers of Jews rather than Idi Amin and Radovan Karadzic. The GOP puts such things in explicitly religious terms and thus appear less rational or calculating. But it's not even that well-hidden in the case of Biden and Blinken given what we know of their careers and lives.
