I think that there would be a whole lot of dead Canadians to round up while that is tried...
Really? You really think so...or you just whistling past the graveyard of reality?
Step 1) Declare a terrorist/infiltration national emergency. Bioterror.
Step 2) Shut down internet, start broadcasting insidious propaganda from Dear TOTUS on Emergency Broadcasting System, newspapers.
Step 3) Take your time. Platoon-strength troops going neighborhood to neighborhood (not door to door.) They get your neighbor's guns on the next block....you don't know anything about it because they've got you isolated. Rinse the blood off the porch and repeat. Then they come for you.
Really? You think you're going to run down the block and break the barricades to help someone you don't even know? Did anybody do it for Waco? Ruby Ridge? Hell no! They were branded "child molesters" and "psychos" etc.
All this big talk about revolution is horsepuckey. Even if we all fight, they have been learning for 20 years in Serbia and Iraq and Afghanistan how to divide and conquer.
And besides. With DADT, all you need is an infiltration rate of 1 in 30, say, to rat out true patriots in the ranks who will not fire on their countrymen anyhow. "Just following orders" in a bio/nuke "emergency" may bring a firing squad. Them vs US?
