The situation is dangerous. Imagine a UN resolution for Great Britain forcing it to cede Scotland, Wales and North Ireland to a "peaceful IS State", ruled by a "moderate leader Abu Bakr al-Baghdadi". What would happen to the rest of Great Britain a few years (or even months) later ? Exactly this (the second Holocaust) will happen if this genocidal "peace resolution" is approved
Are the nasty Americans threatening to stop giving carte blanche to anything Israel does? Who gave americans the right to make up their own minds, how dare they!
In the case of Northern Ireland we made peace with the terrorists, willing to surrender sovereignty to the majority vote in NI. Note we did not attack Eire even when rockets and mortars were being fired across the border, we did not destroy terrorists homes and make their families homeless. In the case of Scotland they got a referendum but liked the Union so much they decided to stay! Israel choose to not make peace when it could, now it may get its reward.
Did you understand the question ? Ceding Scotland, Wales and North Ireland to the IS ? And the IS killed "just" one Briton, while the PLO openly boasts to have murdered "11 000 Israelis". http://www.jewishpress.com/news/breaking-news/abbas-fatah-movement-brags-it-killed-11000-israelis/2014/08/11/
Britain has a permanent seat on the UN security council, we do not need to rely on the USA, however if we did, I somewhat doubt we would be as stupid as to think we could take America's help and then expect their unqualified support no matter what we did. But if we did then we would have to put up with it, and either choose to except what the world wants us to do or fight on alone.
