In 2007 the German professor Bassam Tibi suggested that the Rohingya conflict may be driven by an Islamist political agenda to impose religious laws, while non-religious causes have also been raised, such as a lingering resentment over the violence that occurred during the Japanese occupation of Burma in World War II—during this time period the British allied themselves with the Rohingya and fought against the puppet government of Burma (composed mostly of Bamar Japanese) that helped to establish the Tatmadaw military organisation that remains in power as of March 2013.
