Following his earlier denunciations of US imperialism in Libya and elsewhere, Ron Paul stated today in a NH speech that the murder of US national and al-Qaeda suspect, al-Alwaki, was grounds for impeachment.
"It sets a dangerous precedent" Paul said, and further added "There is no constitutional grounds for the Executive Branch ordering a murder of an American nation without a trial." He stated this this was another 'open door for tyranny'.
Paul has an excellent point about the precedent. The murder of al-Alwaki sets a policy by which American expatriates living abroad can be targeted for murder if they oppose the government---treated as enemy combatants. Worse still, al-Alwaki was murdered in a neutral country by US mercenaries; showing the corporatist-state's willingness to treat all foreign nations as its vassals.
