Baghdad Pact / CENTO (1955)
Britain backed a defense pact linking Iraq, Turkey, Iran, Pakistan and later others against Soviet expansion. It aimed to build a Muslim-majority security bloc across the region.
Iraq's 1958 coup pulled it out, gutting the pact's core.
Renamed CENTO, it faded and formally dissolved in 1979 after Iran's revolution, never fighting as a bloc.
It shows how regional defense pacts can look strong on paper yet unravel when members' politics shift. The Mecca pact faces the same test.
