The Comprehensive Nuclear-Test-Ban Treaty (CTBT) outlaws the testing of nuclear weapons. So far, 183 countries signed the treaty, but it cannot become a binding international law until it has been ratified by all states capable of developing nuclear weapons, of which there are 44 specified in the treaty. Of these states, three (India, Pakistan, and North Korea) have not signed the treaty, and a further six (China, Egypt, Israel, Iran, and the United States) are yet to ratify it.
The recent meeting in Mozambique of the signers of the Ottawa Convention, which bans the use of landmines, has brought the subject of landmines back into the spotlight. To date, 161 countries have signed the treaty, and its aims were included as official United Nations policy in 1999. Long a vocal opponent of landmine proliferation and usage, President Barack Obama opened a review of America’s landmine policy in 2009. He has yet to take a major action, but many Obama-watchers fear he will soon take action to sign the treaty. He would be wrong to do so.
