Israel is in open violation of more UN resolutions and international laws than virtually any other nation on the planet, including, but not limited to, using Palestinian civilians as human shields, torturing and sexually abusing Palestinian child prisoners, settling and stealing the occupied land of the West Bank, sterilizing Ethiopian and African immigrants en masse, targeting and bombing civilian infrastructures, starving an entire population of Palestinians as a result of the deadly years-long siege of Gaza, etc., etc.
The problem with the UN, however, is that while the General Assembly regular passes resolutions condemning Israel’s crimes, nothing ever gets done about it due to the undemocratic structure of the UN. While the General Assembly — which is comprised equally of all the countries on Earth — can pass resolutions, it has no executive power. That power lies with the Security Council which more or less consists of the world’s greatest imperial powers, and who each have veto power over any decisions made by that body.
Therefore, because the US is Israel’s number one supporter and patron, and because the US dominates the UN, nothing ever gets actually done about Israel, even though the UN General Assembly has condemned Israel again and again.
This is also because the US — again, Israel’s greatest ally — is itself actually the most violent, militaristic, and destructive government in the world today. It is responsible for more slaughter, more foreign wars, more instability and violence, than any other nation on the planet. It has a bigger military than the next 20 countries of the world COMBINED, and it uses it … A LOT. And this is not even to mention the constant drone strikes the US uses against countries it is not even in a declared war with, such as Yemen, Pakistan, and Somalia.
But if you don’t understand the nature of US imperialism, than I can hardly expect you to understand the nature of Israeli imperialism — which is, in effect, really an extension of US imperial strategy for maintaining economic, political, and military hegemony over the Middle East.
