If only our aims were so simple and altruistic.
Firstly we only get involved when we have something to gain. There have been many instances in recent times where countries have been having uprisings, civil war or just a plain murderous regime. We sit back and do nothing. In fact it often doesn't even get a mention on the British News. Unlike our veritable lotilla of reporters from every channel in every town and Libyan settlement for example.
Secondly we have a huge number of folk on the payroll actively covertly steering outcomes in countries all over the world whether those governments want it or not.
For double standards you only have to look at the Jews and Palestine. Why hasn't the murder of Arabs been stopped there? (Rhetorical question doesn't need an answer).
No, there is nothing wrong with self determination but it ought to be self not external government installed puppet as in so many other scenarios "we" have been involved in.
I know exactly where you are coming from Varche, but I really do believe, at least for now, that the West has learnt from its past mistakes. I find the USA stance on foreign involvement interesting to say the least, especially on the latest Libyan affair. It may be purely down to economics, and even the USA are suffering from that one! But, I see the Americans becoming far more isolationist after all the criticism, and expense, of "becoming involved".
Their people are now very unhappy about losing loved ones in distant wars, when all they want is a secure homeland that does not fight foreign wars, just as they intended originally and then again before WW2. Times have changed, and no longer does the current administration, as does their voters, want the USA seen as "the bad guys", losing their own people, and spending billions of dollars "unnecessarily" in the process.
History will eventually tell us where this is going and Europe may be unhappy at the outcome!
