who knows man
wahabis will behead, kill children, rape 3 year olds, blow themselves up, take off the heads of innocent taxi drivers for being shias, kill Iranian truck drivers for trying to make a living, massacre entire villages for not growing beards...
We can thank the saudis for this amazing cultural export. Of course the pashtuns of Afghanistan are f'ing nutz in the head, so when you export wahabism to these people they become even worse than saudi wahabis.
As we can see in those pics, no border guard will ever want to be captured by these animals. Iranian border guards are conscripts. They are kids sent out to do their 2 year obligatory military service. People who have just graduated high school with an entire life ahead of them.
They see 300 people coming in towards, they know what happens if they get captured, they know they can't arrest them... so they do the only thing they can to survive in that situation: they defend themselves. This isn't even a case of the guards not trying to let them in. This is a case of self defence on the part of the guards, period.
