That's because the left is willing to employ double standards. We could have easily subdued and occupied that or any other country, but for the ROEs (rules of engagement) levied by the leftist Pentagon, State Dept and Administration that prevented our soldiers from conducting a proper war. The above were so concerned about the delicate sensitivities of the muslims and the UN that our troops had to surrender their lives or risk going to jail (where many sit martyred today) rather than shoot an Afghan "civilian" whom their gut told them was aiding the enemy.
If our present establishment set out to quell a disturbance populated by white Christians, you can bet they would not be so fastidious in respecting such "cultural differences" from the fascist left.
That's true, and don't think they'll behave any differently if they choose to exert force against secessionist American states. In fact, they'd pull their punches even more than they did in foreign wars when faced with having to subdue their own people.
The other dynamic that needs to be factored in, is the reaction of those being subdued. We're not talking about quelling a localized civil disturbance here. We're talking about the U.S. government executing an act of war against a large segment of the country over a civil process of political dis-union.
The very act of them raising their hand to us in such a manner, would forever shatter the civil compact between us. Such an act would give the secessionist states the legal and moral grounds to retaliate in kind - and they would. The resultant death and destruction would destroy any hope of ever achieving the central objective of such an overt act.
It's a risk that I don't believe the powers-that-be will take. As in any war, there's always the possibility that the aggressor will lose - even when they possess superior firepower, etc. The current regime doesn't have the stones to commit unrestrained violence against any foe - least of all, their own countrymen and kin. Even when extreme violence has been committed against them first, their response has been tempered.
It's a stretch to believe that they'll suddenly find the courage necessary to execute a full scale war against a segment of their own people, when those people have done nothing but choose to enact a political realignment.
