No, you're clearly believing what you want despite common sense and clear proof to the contrary. This is a quote from the information that you yourself were referencing: "if a state that we are engaged in conflict with is a nuclear-capable state, we do not necessarily intend to wait until that state uses nuclear weapons first—we reserve the right to use nuclear weapons first in a conflict whether its CW [chemical weapons], BW [biological weapons] or for that matter conventional [weapons]," he said.
Now how do you get "the USA has an absorb first policy" when it clearly refutes that claim? You're an idiot, that's how.
