Ending the war on drugs and legalizing all drugs would effectively completely solve the problem. The border war is entirely the fault of failed US policy.
To those saying "build a fence", you are effectively implying the border needs to be guarded better. This is actually worse for illegal immigration. By enforcing stronger border control, you make it much harder to cross the border - in both directions, this usually means that those illegal immigrants who come to the US, are far more likely to stay. In the past, almost half of the people who crossed the border illegally, went back again within 1 year. This is no longer the case.
