Weirdest Coalitions/Cooperation Agreements?

[CumbrianLefty]

King Sihanouk allying with the Khmer Rouge against the Lon Nol during the Vietnam War. The avowed maoists holding him up as the "people's King" was quite a thing. Even more suprising was that the Alliance actually held up for a while after they won the war in 1975, with Sihanouk becoming the figurehead Monarch of an officially Communist Dystopia led by the "Prime minister" Pol Pot. After the Khmer Rouge went completely insane, he Resigned, but later, after the Vietnamese invaded, he allied again with them as the Government in Exile known as the "Coalition Government of Democratic Kampuchea" supported, this time, by the US, despite them killing 1/4 of Cambodias population and running a state which Kim Jong Un would likely regard as despotic. So a Maoist-Monarchist-U.S. alliance. What beauties the Sino-Soviet split can create.

And most of their allies.

Amongst other things this led to the still surreal praise offered to "Khmer Rouge moderates" <sic> by none other than staunch scourge of Communism, M Thatcher.

They were also joined after 1979 by the KPLNF who were made up of largely of the non-royalist remnants of Lon Nol’s Forces who’d been the anti-Communist resistance to the Khmer Rouge 75-79. Despite the fact they’d deposed Sihanouk and been at war with the Khmer Rouge for a decade. Joined together by hatred of the Vietnamese.

I'm surprised noone has brought up Lebanon. The complicated sectarian power balance means that parties that have often been shooting at eachother are also in government together.

I believe most of the Japanese coalitions of the 1990s were bizarre; most notably, the unstable coalitions between the 1993 and 1996 Diet elections, which regularly consisted of more than three parties, usually including both Socialists and conservatives, including Komeito--a party which was seen by many as an unconstitutional party for its affiliation to a specific Buddhist sect, Soka Gakkai.

Not exactly a coalition, but after the 2013 Bulgarian parliamentary election, the ultra nationalist, anti-Turkish Ataka party helped a BSP-MRF (a nationalist Turkish party) coalition, which had exactly 50% of seats, form a government by abstaining in the vote to form the government
