Was Bush's war against Iraq wrong. Was the liberation of Kuwait from Sadam Hussain's oppression wrong?
No, it was not illegal because Bush sought and got approval for military action from congress making it constitutional. Then the USA got the UN security council to authorize force for the restoration of sovereignty and territorial integrity of Kuwait, a UN member state.
Was the intervention by Cinton in order to prevent mass blood shed and the spread of civil war in Kosovo wrong.
It was more than wrong, it was illegal. NATO's charter was violated, NATO had no charter authority to act as it did. In addition, Clinton refused to get UN Security Council authorization for military force before hand, thus making NATO's military action illegal under international law. NATO imposed a threat of war in the form of an ultimatum against the territorial integrity of a UN member state, also a high crime, the same crime for which Nazis were hanged for. Clinton also refused to get authorization for the air war from congress making any military action unconstitutional. When Clinton did take it to Congress (after military action began) Congress voted against military action thus denying constitutional legitimacy to military action by the USA over Kosovo.
You do not have to take my word for it because I am partisan. Tony Blair's own Labour party controlled Parliamentary commission came to the exact same conclusion House of Commons Foreign Affairs - Fourth Report [UK Admits NATO's Kosovo War Illegal].
the ICJ case continues, there will be another hearing this february.
The NATO/ U.S. reaction in Kosovo despite the U.S. Congress's vote to not take military action could have resulted in another Rwanda. A show of GRIT on the part of Clinton to intervene and not have a repeat of Rwanda. You forgot to mention that the President of the United States has the power of a Veto in regards to Congress's vote and exercised that power. If he acted illegally why was he not impeached???? A show of GRIT and the ability to take the bull by the horns and to act on it because of what happened in Rwanda. This intervention into Kosovo in my opinion has saved countless amount of lives from the eventual civil war that would have taken place and it would have been another Bosnia. I was one of the first from my part of the world to enter Kosovo. It would have been a mess but of course you have far more experience sitting there in good old California with your finger on the pulse while reading left wing magazines. Put yourself in Clinton's position. Morally and politically could you have lived with yourself knowing that you could have acted while seeing thousands of dead in Kosovo on both sides i.e. just like what happened in Rwanda and Bosnia. NATO intervention was a very necessary thing.
NATO intervention i.e. the first NATO Air strikes on Bosnian Serb positions around Gorazde in Bosnia (1994) saved the lives of approx. 45 thousand Bosnian Muslim civilians (HUMAN BEINGS)who for the most part defending themselves with hunting rifles. Gorazde was targeted to be over run by the Bosnian Serb Army who brought a lot of armor. Could have been another Srebrenica but worse.
