Shouldn't our National Guard be armed at the border now? Isn't his an act of war?

You're right and I agree wholeheartedly with you on this issue, our Guardsmen are being restricted from such things as defense of the country defending the nation from armed incursion as has happened on numerous occasions. Two Border Patrol Agents were convicted of shooting a drug runner that attempted to cause them harm. Why are our guard dogs being muzzled? I cannot answer that question, but I can tell you there is no justifiable reason for this sort of restriction, our nation is being harmed by this open border. Drugs, terrorists, rapists, and murderers are coming through and our government, in their very finite wisdom has deemed the rights of cartel lords and cocaine mules to be more important then the safety of the American people.
