RUSSIA - Russian President Vladimir Putin has recently warned the United States not to withdraw from their nuclear arms control treaty, noting that doing so would prompt the Kremlin to “hit back fast,” reports Reuters. “From our side, the response will be instant, and I want to warn, symmetrical,” cautioned Putin during the high-profile televised Valdai discussion with foreign academics in the Black Sea resort of Sochi, on Thursday. His comments come amid allegations that the Clintons facilitated the sale of 20 percent of US domestic uranium production to Russia under the administration of former US President Barack Obama. According to Reuters, Putin accused America of betraying the Kremlin by not reciprocating what he described as the “unprecedented access” Moscow granted Washington to its secret nuclear sites in the 1990s.
