I’d go with something different:

Does the US Constitution mean what it says or what we want it to say? This gets into judical activism, and also judical selection process.

Should election campaigns be publicly funded? This can get into whether extremists should receive public funds in order to eliminate the perception that major candidates are being bought.

Should there be limits on contributions to election campaigns? Is this denying people free speech?

Your question about pulling out before the initial goal is accomplished would be an interesting one – you could outline the initial goal and trace the changes that have occurred in policy over the course of the engagement, until it reaches a point where the war presently being fought bears little relationship to the war that was originally being fought.

It’s a worthy topic for a scholarship essay – good luck with it.

Will The current nuclear agreement between India and the USA spark another arms race, this time, in the nuclear field in the Asian countries, especially Russia, Pakistan, China and Korea?
