Keith from the way you take the "party" line in this thread it is obvious that you believe the politicians every time.
The intervention in Libya ostensibly was on humanitarian grounds. The ensuing death toll suggests that the stated aim was not achieved.
But if you follow the munneee a different, far more plausible scenario, unfolds. NATO intervention may have been motivated by Gaddafi's attempts to establish a unified federation of African states that would use the gold dinar as its currency and demand that foreign importers of African oil pay in gold. (What does that do to the almighty dollar?)
Iraq was invaded for a number of reasons, The WMD angle was merely a pretext. A summary is here
reasons
Syria. A spontaneous uprising mutating into a civil war we are told.
Well here is another view:

I can assure you that I simply do not believe these events developed as we are led to believe. It is not a fight for people's rights, it is a battle to subdivide and conquer. The people on top of the sand are not the issue, the oil under the sand is! Syria is stalling a pipeline route for Saudi oil and Quatari gas straight to europe.

If I was cynical I would say Afghanistan is a part of the equation too. Some would argue the opium is a cash crop for the CIA. When I was in Singapore in the early to mid 70's there were many Bird Air, Air America and other dodgy transports cluttering up the tarmac at Seletar , and the Golden Triangle was a hop skip and jump up the road.(Coincidence?) The old Gil's Grill in the Shaw center on Orchard road hosted a variety of strange people beside the oilfield and I used to hear some totally outlandish tales there, some of them likely based on reality.

Having had a bit of a wandering life I tend to treat official stories with permanently raised eyebrows. The world simply does not work the way the media would have us believe. As I repeatedly say(to no avail)yes/no, black/white rarely exists. The truth resides in a grey fog. I have no idea what the true story is most of the time, but my "bullshit " detector is highly developed and generally points in the vague direction of what actually happened. The only certainty is that the pretext for starting wars is generally false.(not always,   but usually)
There is a saying "All wars are Banker's Wars" The arguments in support are quite strong.

In conclusion Russia, China and Iran are dumping the dollar for oil purchases. Western(American) Bankers will not take kindly to that!
You appear to reside in the perfect as opposed to the actual world.

I think a cursory study of the Iran Contra affair is a lesson in the perfidy of politicians and their underlings.
