What do I do? I toss a tomahawk missile or two at a camp somewhere sandy and hot while hoping one or more of them don't go off course and hit Iran or Turkey. Oops. If it looks like I need more help, I get my wife to say something that makes it sound like she's going to be setting policy on a hotly contested subject, maybe abortion, health care, or education. Then based on the polls, I either support her, or have an affair showing that I don't support her stand on that controversial subject. If necessary, I ask someone to leak to the press that my daughter is either pregnant or just lost her virginity, or something to that effect.
If it gets too bad, I hold a rally supporting veterans and find someone elses medals to either symbolically throw away or pin on someone, depending on if the polls say veterans should be proud or pissed off that week. Then I find ANY decision that a political opponent recently made, and make a media soundbite to the effect of "Only HE would come up with a childish idea like that... He should have asked a few experts first." regardless of what the decision was.
I'd also send out some memos to the CIA and FBI telling them to "take care of things" regarding the persistent but non-specific threats. There are a lot of Muslim countries and even some countries with hardcore communist insurgencies so I'm sure they can generate a few headlines in some of them. I'll make darn sure they don't focus on the Phillipines though, because they're determined to wreck their own country before getting to ours so that's just a waste of effort and good PR opportunities. At the next round of budget talks, I'll force through a small but noticable funding increase for those who I've told to "do something", just to prove that I increased funding for the groups responsible for national security. Cutting aid to countries who aren't outwardly hostile but who aren't part of "the club" can help pay for the CIA budget increases.
Then I try to make sure I don't support or object to the policies of any other country until the last few months of my term. Status quo is my watchword.
I almost forgot - make my party's nomination for the next term look like a fool, and then sell my stocks right after the opposing party's candidate wins. Buy low a few years later and ride the wave through retirement.
Anything I miss?
