I don't agree with this, even in the slightest. Have you been in the military? Do you know how many will follow unconstitutional orders if there is no resistance vs. following those orders when going against some resistance?...resistance which makes the troops do things that they know are unconstitutional and against their oath? That is the beauty of a volunteer military force. Unlike many politicians and bureaucrats, the majority of troops take their oath to the Constitution seriously.
And the people would not just be a guerrilla force, but that same military is made up of our own sons, daughters, brothers, sisters, etc. Also, we are the actual logistics supply for that same military...do you think they are just going to destroy their own logistics supply without a second thought?
Have you seen how things go here domestically, when just a few people can defend themselves? It may not have helped the people in Waco or Ruby Ridge to be armed, but look at the push back that happened for years as the result of those actions. Unarmed, those people would have been rolled up by the ATF (or IRS, FBI, etc in the past) and thrown in jail without anyone knowing about the govt's overreach, and the govt would have just become further emboldened. Also, all areas of this country have a sheriff which can stand up against the Feds when they over reach, but it seems like an armed standoff with the feds is often when the sheriff first gets notified or involved.
