Classically Liberal Stance

Well, as you may or may not know, my topic throughout the summer has been the Merida Initiative. Shortly after I chose this topic, President Bush signed into law a bill that provided funding for the wars in Afghanistan and Iraq to which the funding of the Merida Initiative was attached. This was an interesting occurrence because I was at first unsure as to whether or not that destroyed the controversial nature of the topic. I mean, once a thing has been decided, what's the point of arguing about it anymore, right? I was able to get by in the first two units because the aim was to outline and analyze other peoples arguments on the topic and there were plenty of those left over. Now for this unit, I am again facing my original concern. With this in mind, I began thinking of how the initiative is still a relevant topic of discussion. One thing that I could think of was the future of the U.S./ Mexican relationship in the way that it deals with illegal border traffic of humans and goods.
The amount of funding that the initiative supplies is, admittedly, not significant. Many if not all of my sources pointed this out. Why, then, are we spending our governments brain and political power on something that many are not expecting to be all that significant in its impact on the drug trade. I would not like to sound like someone who believes in conspiracy theories, but I would like to look at this question logically and see if something is there. My initial suspicion is that a small cooperative effort will pave the way for more significant and large scale cooperative efforts in the future. At some point in the future, our attention will focus back on the Drug War in a big way. The War on Terror will go quiet eventually and the War in Iraq had better start packing its bags after Obama takes the oath in January. Drug Wars are wars that Democrats like to fight. They are acceptable wars. I would rather the U.S. not be armed with better relations with Mexico once the Drug War becomes mainstream again.
Qualifier: I do not smoke pot.
So, let me try to cram this into a nutshell; my "original" argument is... the U.S. should not claim any successes relating to the Merida Initiative because it would warrant future cooperative efforts with Mexico of unknowable scale that could increase and continue the disastrous effects on the people of the United States resulting directly from the War on Drugs. My audience would preferably be a few of my friends on my back porch, but to take that and make it more appropriate, I would say that my target audience would be semi-well informed, open minded and economically literate 20-40 yr olds. With a topic such as the Drug War at hand, I may have to use lots of appeals to the sense of justice in the readers. I think I can make some reasonable economic arguments as well.
Let me know if my nutshell is far to big or far too small for a 4-6 page paper.
