The Russian mafia is ruthless, blood-thirsty and without morals. Plus, there are two kinds of mofia that most people overlook. One is the business mafia, those are the guys you run into while doing business in Moscow and such that suggest and assist with the bribs that are necessary to conduct normal business. They are also involved heavily in bank fraud both in Russia and abroad, as well as a peice of the car theft ring, vodka sales, etc...They'll kill, but only when they have too.
Then you have their mortal enemies, the Chechin mafia -- MUSLIMS of the worst kind. They are just as connected but have their central activities in illegal arms trade, drugs, prostitution, extortion, etc...Both mafia groups are connected to the military in one way or another, and have the local police wired for sound and on the payroll. Both groups are extrememly wealthy, the former more so and better organized with slightly higher morals. The MUSLIM Chechin mafia is segmented and disorganized with fringe groups acting in cells all over central and eastern Europe.
Given my experience with these groups, I'd have no problem believing that the MUSLIM Chechin mafia has indeed sold and exported nuclear weapons out of Russia, and materials needed for their construction. Draw what conclusions you'd like, but I consider it as fact that our enemies are so armed. Additionally, I have no doubt that those weapons are south of our border, if not already in our county. Imagine the amount of cocaine that is transferred from S.America to Europe and the amount of heroine that is transported from Europe to S. AMerica only to end up in our country. Hundreds of thousands of tons. If someone actually planned on taking in one of potentially several nuclear devices, can anyone confidently say they haven't already arrived on US soil, or will at some point in the future?
Complete and total extermination of the terroristically inclined is the only answer. That and a hard-line crackdown on our borders, and illegals in this country.
