Christ teaches; Matt 24:6 And ye shall hear of wars and rumours of wars: see that ye be not troubled: for all these things must come to pass, but the end is not yet. 7 For nation shall rise against nation, and kingdom against kingdom: and there shall be famines, and pestilences, and earthquakes, in divers places. 8 All these are the beginning of sorrows."
Wars are going to be a feature of mans future as they have been a feature of his past. We observe how close Obama and his followers are to war with Syria and that's not going to be the end of it. Iraq, Afghanistan and the constant battle with Al-Qaeda and Taliban will continue and western nations will 'feel the need' for the necessary reactions to particular belligerence. Politicians will talk themselves into more wars and probably feel themselves to be justified and righteous in their 'cause'.
As for Israel and war - I don't think that anybody doubts that it is on the cards. Considering the muslim countries attitudes towards Israel, and the fact that they surround Israel, that particular fuse will definitely detonate one day regardless of what western politicians say.
