government's actions. The treaty was subsequently ratified by parliament. In his decision, Justice Sayem referred to the Vienna Convention on the Law of Treaties. The Land Boundary Agreement was finally implemented in 2015. Japan became a major aid provider to the new country. Mujib attended Commonwealth summits in Canada and Jamaica, where he held talks with Queen Elizabeth II. The Soviet Union supplied several squadrons of MiG-21 planes for the Bangladesh Air Force. Although Israel was one of the first countries to recognise Bangladesh, Bangladesh strongly supported Egypt during the Arab-Israeli War of 1973. In return, Egypt gave Bangladesh's military 44 tanks. Algeria facilitated Bangladesh's entry into the OIC by brokering talks with Pakistan. Left-wing insurgency At the height of Mujib's power, left-wing insurgents from the Gonobahini fought against Mujib's government to establish a Marxist government. The government responded by forming an elite paramilitary force called Jatiya Rakkhi Bahini on 8 February 1972. Many within the Bangladeshi military viewed the new paramilitary force with suspicion. The new paramilitary force was responsible for human rights abuses against the general populace, including extrajudicial killings, shootings by death squads, and rape. Members of the Jatiya Rakkhi Bahini were granted immunity from prosecution and other legal proceedings. The force swore an oath of loyalty to Mujib. One party state Mujib's political philosophy dramatically changed in 1975. Elections were approaching in 1977 after the end of his five-year term. Mujib sensed growing dissatisfaction with his regime. He changed the constitution, declared himself president, and established a one party state. Ahrar Ahmed, commenting in The Daily Star, noted that "Drastic changes were introduced through the adoption of the 4th amendment on Jan[uary] 25, 1975, which radically shifted the initial focus of the constitution and turned it into a single-party, [p]residential system, which curtailed the powers of the [p]arliament and the [j]udiciary, as well as the space for free speech or public assembly". Censorship was imposed in the press. Civil society groups like the Committee for Civil Liberties and Legal Aid were suppressed. The Bangladesh Krishak Sramik Awami League (BAKSAL), meaning the "Bangladesh Farmers Workers Peoples League", became the only legal political party. Bureaucrats and military officers were ordered to join the single party. These actions profoundly impacted Mujib's legacy. Many Bangladeshis opposed to the Awami League cite his creation of BAKSAL as the ultimate hypocrisy. The one party state lasted for 7 months till Mujib's assassination
