Responsibility to Protect
When a state poses an international threat to security or an internal threat to the freedom of its people, the international community has the responsibility to intervene and protect human rights and international security. This choice requires a robust forward presence of the US military. Additionally, you, as President Bush, would alert the international community to an American commitment to protecting ideals of human rights and security.
As President George W. Bush, you have made a series of choices dealing with America's counter-terrorism policies. Let's analyze your choices and their implications.
Your decision to fight a single large war in the Middle East was strategic. The US military will not be overstretched, thus your mission has a higher probability of success as the US is able to commit a greater percentage of resources to the intervention. The war will still be relatively long and costly, but there is a good chance the US will successfully drive out the Taliban and strengthen the central Afghani government in Kabul.
Furthermore, after a new round of IAEA inspections, it is found that Iraq is not pursuing nuclear weapons, but that it maintains a stockpile of chemical weapons that could be transferred to terrorists. Saddam Hussein decides to pursue stringent safeguards and allow future IAEA inspections in exchange for the lifting of Western sanctions on Iraq. However, Iraq could easily hide a smaller stockpile of chemical weapons if it so chooses.
Illustrating American commitment to the responsibility to protect will boost American credibility among its allies. This approach will also allow the US to pre-emptively exert force to stop terrorist organizations from gaining power. The war on terror will likely never end, but America will be able to minimize the probability that a terrorist attack on American soil is successful.
The issues of terrorism and weak/failed states do not have easy solutions, but you have done a good job. You have sufficiently dealt with the threat of terrorism. Furthermore, you have assuaged the American public and will get re-elected in 2004. The decision to fight one war means you minimized the length and costs of the mission.
