Given Yemen's recently awarded position as a thriving hotbed of international terrorism and home of the newly patented "butt-bomb" strategy, it's reasonable to question American motive for becoming involved in the region. The past decade, if nothing else, has provided us with a healthy dose of skepticism when it comes to our leaders claims of the need for pre-emption.
I'm approaching this with an open mind, willing to consider any of a number of possible explanations.
Although Yemen is rich in minerals, it's oil producing capacity in negligible (
http://www.worldtribune.com/worldtribune/WTARC/2009/me_oil0969_12_16.asp). Its capacity to export oil, according to the link, is predicted to cease by 2020.
Its strategic value by virtue of geography is virtually non-existent since the end of the cold war.
It's total population is estimated at ~18 million, with only 6 population centers having populations greater than 100,000. Infrastructure within the state is limited, and its population exists largely as a tribal society.
Why be concerned with such a rinky-dink country, then?
Regional stability is an issue, which is also of interest to our ally and Yemen's immediate neighbor, Saudi Arabia. Although I fail to see how this would be politically expedient to justify American intervention within the region, enough back room deals are reached between the West and Saudi Arabia to flag this notion as a possible contributing factor.
There is also the possibility that claims of Al Qaeda activity in the region are in fact true. Two factors which might influence the rise of Al Qaeda in Yemen are: 1) the elimination of Al Qaeda operatives in Saudi Arabia, driving its members into neighboring Yemen; and, 2) the 94% reduction in US financial support to Yemen since the decline of the Cold War. In essence, because Yemen lost its strategic value, it also lost financial support, arguably creating fertile grounds for Anti-American sentiment and the recruitment of mujhadeen.
I dunno, but claims of Al Qaeda in Yemen seem plausible, although that would also appear to be a consequence of short-sighted American policy within the gulf region.
An interesting background and analysis of Yemen dated from 1996 can be found at
http://permanent.access.gpo.gov/lps12810/00187.pdf It's an analysis written by a colonel at the Strategic Studies Institute. Due to the date of publication, presumably it precedes any efforts to gin up justification for current activities in the area.
