There are only a couple solutions and none of them are good, other than China taking him out..
#1 wait till he actually hits something with a nuke..then take out the country..
#2 make a preemptive strike and start WWIII, us against everybody else....or pretty much everybody else...
Other than these I don't really know how you handle this... The money is probably coming from Iran, you know the 150 billion in cash Obummer gave them last year....
