It is no secret. The US retains the right to use nuclear weapons first if we believe it is justified to defend this country. It is our stated policy. We will not wait until we are attacked by nuclear weapons.
I won't address the rest of your scatological comments, which have nothing to do with the subject of preemptive attacks.
What an absurd response. Tactics are everything, and there is no stated U.S. policy that matters. What matters is what is in NSPDs of the President and some classified material.
