Historically, we know that prohibition of substances that defy control(i.e. easily manufactured) is virtually impossible. Alcohol products(home made brews, wine, gin, whiskey..you name it) are fairly easy to produce anywhere. But no where near as easy to produce as pot. When you just step out into your back yard, grab a few leaves off your own bush, dry them and light them up, it leaves little for even those of the least of metal faculties.
As for the War on Immigration, that is controllable. What's lacking is the will. Why would an illegal come here if there was no work for them, no free benefits provided and no automatic citizenship for those born of illegals here. We just need to make the penalties so severe that no one would risk it.
Just as with the War on Terror, we need to take it to them where they are, not wait until they get here. Does anyone think we can't today kill off most of the coca plants in Columbia with a year-long campaign of aerial spray erradication? They only grow in the mountains there.
Being a realist is good but I think there needs to be room for taking a stand on principles as well. Otherwise we are going to have to give up prohibiting other “substances that defy control” such as prostitution, gambling, and meth. As for the War on Immigration, I would say it is no easier to win than the War on Drugs and the same response (yours) can go a long way in controlling both. “Make the penalties so severe no one would risk it” after all, few LEO’s are being killed in the War on Immigration compared to the War on Drugs.
