How long before US courts are completely subservient to international courts? Already in process.
How long before individual private property rights take a back seat to corporate development rights, and then are abolished altogether? Witness the eminent domain case in Connecticut.
How long before First Amendment political speech is deemed inappropriate, improper, and finally downright illegal? Campaign Finance Reform set that precedent nicely.
And finally, how long will it be before the Second Amendment is "suspended indefinitely" due to some domestic emergency (probably another terrorist attack)? How long before Americans are encouraged to "voluntarily" turn in their guns at the behest of being loyal to the administration -- whoever is in office at the time -- and under the threat of confiscation?
Because you can't subsume American courts to foreign influence, abolish freedom of speech and private property rights in earnest with 200 million guns floating around in private hands.
Just make sure your weapons are secure, your ammo is dry, and nothing is all in one place.
Don't forget to store tuna fish and powdered milk under the bed.
