Massacre at the Fort Hood: was it a kind of revenge?

It turns out that major Nidal Malik Hasan, the sole suspect in massacre of 13 fellow US soldiers in Texas had reasons for the aggression. Don’t get me wrong, I’ am not justifying his deed " undoubtedly it is awful! But, you know, that was a kind of his reply for the unfairness in the US army. The fact is Hasan had got to know from his pal in the Pentagon (evidently this guy takes quite high position) about the plans of the US army headquarters - hard purge in the US army. First of all they are interested in revelation and tracking of the Arabian soldiers " expatriate Muslims and in driving them out from the stuff. Well, it is safe to say that Muslims can forget the idea about a successful military career and about service in most valuable divisions. The dropout was planned as it was with Hasan: hotspot missions in Iraq and Afghanistan, where they will simply be killed or in case of refusal to go there it will be possible to cancel their contracts. But who could expect that enraged Arabian military psychologist will make butchery of it. It’s a pity but all that have led to the death of innocent people.
What’s more scaring imo is that this may be well followed by other similar incidents involving Americans of the Arabic whose rights are violated in USA.
