Following the deterring effect of Operation Vantage (1961), Kuwait gained its recognition by Iraq in 1963. Both countries had ongoing border disputes throughout most of the 1960s, although often resolved and restrained within the history of Arab solidarity. Since 1967 and during 1973, despite the unstable history between the Kuwaiti and the leadership of Iraq back then, the Kuwaiti military acted in alliance with the Iraqi military during the Six-Day War and participated with a token force during the 1973 October War of the same year.
