There's still this thing called the Universal Declaration of Human Rights that says "Everyone has the right to life, liberty and security of person". The United States voted for it in 1948.
At least in the United States there's a clear solution to the American government breaking the constitution, and that's an armed revolt as a last resort and a finally new government (but not necessarily new constitution).
I'm absolutely not suggesting Americans do this. it's a just a consequence outlined both in history and the constitution.
