GLOBAL CONNECTIONS: the Near/Middle East
1961: As Britain ends its protectorate in Kuwait, Iraq threatens to claim its neighbor for its own.

After Kuwait gains its independence from Britain on June 19, President Abdel Karim Qasim of Iraq asserts a longstanding Iraqi claim to Kuwait. Kuwait seeks and receives British military support, which in the end is not needed, as Iraq does not launch an offensive. Iraq never formally withdraws its claim, however, and in 1990 invades Kuwait and claims it as Iraq's 19th province.
