The destruction of the U.S. military didn’t begin just under Obama (or Bush). The Clintons paved the way for disarmament. The same thing that happened in Tennessee and in Fort Hood and is bound to continue happening elsewhere.
From 2009 with relevancy today:
Time after time, public murder sprees occur in “gun-free zones” – public places where citizens are not legally able to carry guns. The list is long, including massacres at Virginia Tech and Columbine High School along with many less deadly attacks. Last week’s slaughter at Fort Hood Army base in Texas was no different – except that one man bears responsibility for the ugly reality that the men and women charged with defending America were deliberately left defenseless when a terrorist opened fire.
