Fort Monmouth, New Jersey, is an odd place to discover the possible fate of Iraq. But the fort, a 90-year-old Army base in the midst of suburbia, plays host to the Army's communications command, which has quite a lot invested in that country's future. For the moment, the United States has 140,000 troops stationed in Iraq, where they shall remain, according to the Bush administration, until the Iraqi government can defend itself against internal subversion and mounting sectarian conflict. Having invested the lives of 2,700 troops, the health of another 20,000, and about half a trillion dollars in that effort, nobody in the United States government is willing to predict when that day will arrive.
