When the question was both rhetorical and lazy, that is what one calls it. Oh, and please learn some English grammar; "dialogue" is a noun. The quality of your prose reflects very badly on the validity of whatever rationale you think you are communicating that in fact you are not. Sic:
Quantifying impacts of American Imperialism needs to be our bottom line.
Kindly propose a metric for "quantifying" an outcome with both multiple and intangible variables.
The American leadership standpoint should ensure its people with the day-to-day security to the International stage.
This is a nonsensical statement. You are so addled as to be unworthy of debate. Really.
Your anal musing lacks content validity. Your issues, although precipitous are more qualitative in scope, mere post positivism flailing. Your disquisition enshrines ambiguous, infinitely complexities, variables and is open to interpretation only by you.
So shrug off, and loom into your own wallowing.
