The United States and its western allies are unable to resolve their internal problems and economic crises and try to project the blame on others, a senior Iranian parliamentarian said, adding that Washington\'s recent accusation against Tehran serves the same purpose.\"The US intends to project the blame for its problems through its new scenario against the Islamic Republic of Iran,\" member of the parliament\'s National Security and Foreign Policy Commission Mohammad Reza Khabbaz told FNA on Wednesday. \"Due to its internal and foreign problems, the United States is resorting to any tool and instrument to get rid of its deteriorating conditions today,\" he added. Meanwhile, Khabbaz underlined ineffectiveness of the US doctrine, and advised the American officials to change their wrong way and admit that they have erred and lied to the world people after the World War II and apologize for them. His remarks alluded to the US allegations that Iran had attempted to hire a Mexican drug gang to assassinate the Saudi ambassador to Washington, Adel Al-Jubeir. Two men were charged in New York federal court last week in the alleged plot. Manssor Arbabsiar is a 56-year-old naturalized US citizen. In May 2011, the criminal complaint says, he approached someone he believed to be a member of the vicious Mexican drug cartel, Los Zetas, for help with an attack on the Saudi Ambassador to Washington Adel al-Jubeir. The man he approached turned out to be an informant for US drug agents, it says. The government charges that Arbabsiar had been told by his cousin Abdul Reza Shahlai to recruit a drug trafficker for a hitman job.
