has stated that he will not "compromise when it comes to clean air, clean land, or clean water." Johnson supports nuclear energy and fossil fuels, but has stated that the government has a role to protect Americans against businesses that would harm human health or property, including environmental harm. Campaign finance Johnson opposed the U.S. Supreme Court decision in Citizens United v. FEC, allowing unlimited corporate independent expenditures on political campaigns, while also encouraging full disclosure of such expenditures. Fiscal Johnson has said that he would immediately balance the federal budget, and would demand a balanced budget amendment, but maintained a state deficit. Healthcare He has stated he supports "slashing government spending", including Medicare, Medicaid, and Social Security, which would involve cutting Medicare and Medicaid by 43 percent and turning them into block grant programs, with control of spending in the hands of the states to create, in his words, "fifty laboratories of innovation." He has referred to Social Security as a pyramid scheme. He has advocated passing a law allowing for state bankruptcy and expressly ruling out a federal bailout of any states. Federal Reserve Johnson has expressed opposition to the Federal Reserve System, which he has cited as massively devaluing the strength of the U.S. dollar, and would not veto legislation to eliminate it – although he has stated that no such bill is likely to come out of Congress during his administration. He has also supported an audit of the central bank, and urged Members of Congress in July 2012 to vote in favor of Ron Paul's Federal Reserve Transparency Act. Foreign policy In his campaign for the Libertarian Party nomination, he stated he opposed foreign wars and pledged to cut the military budget by 43 percent in his first term as president. He would cut the military's overseas bases, uniformed and civilian personnel, research and development, intelligence, and nuclear weapons programs, while maintaining an "invincible defense." Johnson opposes U.S. involvement in the War in Afghanistan and opposed the U.S. involvement in the Libyan Civil War. He has stated that he does not believe Iran is a military threat, would use his presidential power to prevent Israel from attacking Iran, and would not follow Israel, or any other ally, into a war that it had initiated. While Johnson views the Islamic threat to the US as overrated, he has been openly advocating for greater diplomacy with China
