For Sarin they’d have to be protected and also carry antidote for emergencies. The antidote is jumbo shots of atropin and doesn’t work all that well.
Often Sarin is laid down in binary form, that is, the load is harmless until it hits the target. But even then, the wind can turn on you.
Would sarin use usually be detectable in neighboring countries because of the wind?
If so it’s doubly stupid that the Obama regime guy said it’s none of our business if sarin is used on Syrians - unless we’re throwing any of our allies in the area under the bus.
And if Obama is providing the means for the rebels to use sarin, everybody in the area would see it as a steaming pile of poop from Obama, wouldn’t they?
Just out of curiosity - is sarin something that could have been brought into Venezuela by Hamas and Hezbollah agents flown on direct flights from Iran? Is it bulky and dangerous even in binary form?
Can UAV’s be adjusted to deliver sarin?
