Here Is My Plan
1) Steal a Transporter.
2) Steal Hermione's Time Turner.
3) Modify both devices to include remote "bugs" for placing on victims.
4) Use two devices to infiltrate White House and [make someone else] place bugs up GW Bush's rectum, where no one will ever think to look for anything other than his head, which no one values anyhow.
5) Use two devices to make GW Bush spend one dinner hour each day with the family of a soldier killed in Iraq.
