What happens Now that Osama is gone?

I congratulate Obama and the Navy Seals, the intelligence services and the entire military for killing of Osama Bin Laden. He deserves to rot in hell next to Hitler and Stalin. However, we can not forget that he was not the one that carried out the terrorist acts, which means there are more enemies of this country out there that will kill Americans at any chance. Not to mention the war next door that seems to be spilling over into the southern states. Of course im talking about Mexico. The violence is increasing each and everyday becuase of the drugs. I think one solution to decrease the violence is by legalizing weed. There are estimates that the cartels make up to $60 billion a year of the drug. if it is legalized there would be no need to buy it illegal and Americans would not have to get it from these dangerous cartels. IT would create a new bussinesses, create jobs and would be an extra income of taxes. The government could control it just like cigs and alcohol. Set rules anr regulations. The violence would decrease dramatically because these cartels would no longer have the funding that they need to run this drug war. I forsee Mexico being a major problem in the coming years if something is not done about it.
