Some UN Blue Hemet peacekeeping operations had limited success. But mainly Washington has used the UN for war, such as the Korean War and Washington's Cold War against the Soviet Union. In our time Washington had UN tanks sent in against Bosnian Serbs during the period that Washington was dismantling Yugoslavia and Serbia and accusing Serbian leaders, who tried to defend the integrity of their country against Washington's aggression, of "war crimes."
The UN supported Washington's sanctions against Iraq that resulted in the deaths of 500,000 Iraqi children. When asked about it, Clinton's Secretary of State said, with typical American heartlessness, that the deaths of the children were worth it. In 2006 the UN voted sanctions against Iran for exercising its right as a signatory of the non-proliferation treaty to develop atomic energy. Washington claimed without any evidence that Iran was building a nuclear weapon in violation of the non-proliferation treaty, and this lie was accepted by the UN. Washington's false claim was repudiated by all 16 US intelligence agencies and by the International Atomic Energy Agency inspectors on the ground in Iran, but in the face of the factual evidence the US government and its presstitute media pressed the claim to the point that Russia had to intervene and take the matter out of Washington's warmonger hands. Russia's intervention to prevent US military attacks on Iran and Syria resulted in the demonization of Russia and its president, Vladimir Putin.
