The west can , and has, the capabilities needed for a full scale destruction of militant Islam,but... That would soon spread into a Genocide, and the West has to many idealogical restraints to take such action.
Thus, militant Isalm will always excist in the middle East, always. But, with the future oil cirsis soon arising in the coming years, the Western power , the United States, with about 0.5% of the world population, but consumes 25% of this planets fossil fuels.The strange fact is, ironicaly, all this rebuilding schools, and retrubution for 9 11 , and the coalition rebuiliding Iraq, this will go all out the window come the dawn of the oil crisis.
If you still dont get what I am saying then answer this, militant Islamic leaders have ties with some nation who have massive amounts of oil,so, even though we in the Western world, and in China buy from them. These leaders still get filthy rich with funds to continue attacking the west.And as backwards and primitive as they seem, when the oil lines drip dry some, possibly 10- 15- 20 years from now, they will be better off than the Energy starved west, and will gain the upper hand, since they dont live around the black smelly dirty gold we call oil.
When gas reaches $160 a barrel, the Average American will be paying
$5.00 a gallon, and will be more willing to go into civil unrest for gas.Buses trains and planes and ships will stop moving, the whole medication industry will be put at a almost standstill.
However the Average Muslim, will go ahead with their average lives, almost completely uneffected , and the extremists, who dont even think about using gun oil, will be more than happy to exploit security gaps in the west due to energy starvation, adiction to fossil fuels will be the biggest threat to the quality of life for American and citizens in other developted nations and a far as I know, hopefully the Muslim Extemists dont know this yet.
