Here we depart..Israel is the prime target of the Arabs,their major fixation has always been the Jews.The practicalitys of logistic would make it almost imposible for the Teleban to smuggle a warhead into or even close to Israel.
I don't think that the Muslim Brotherhood or any of the other Arab terror groups give a fiddlers fart about fallout on the Arab street,If they're willing to kill their own children as suicide bombers they'll kill anyone.An international outrage would be meaningles to them and the Arab states would either say nothing or cheer them for their victory over the Jews.
I agree that they would try for an American base if they had a Pakistani nuke and the bigger the better .America has radiation detectors all over the place and so does Israel.I would imagine that Bagram AFB has detectors or will soon have them in lite of the current situations in Afghanistan.
With Bin Ladin dead It will all be over soon with the UK and Germany withdrawing their troops from the region giving Obama a perfect excuse to retreat and call it a wash.The Taliban will move in, decalre victory and return to the old tribal ways ...It has come full circle, the Arabs will have Afghanistan back,we have avenged our honor for 9/11 and the beat goes on .
The Saudi's have recently invested in radiation detection equipment for their border stations with remote static 'sniffer' and aircraft to detect radiation from likely desert transit routes .
Any Nuclear warhead radiates gama rays as part of it's decay process that are easily detected .The only way to stop or limit the radiation is heavy lead shielding and makes them very heavy to haul anywhere and easily spotted by portable xray detectors .
