Washington: US senators were divided in their assessments Thursday following a classified briefing on American airstrikes on Iran's nuclear facilities, with Democrats questioning the Trump administration's claims while Republicans defended the operation's success. According to Anadolu Agency, Senate Democratic Leader Chuck Schumer criticized the lack of a "coherent" strategy, saying he "did not receive an adequate answer" when questioning President Donald Trump's claim that Iran's nuclear sites were "obliterated." Schumer emphasized the importance of enforcing the War Powers Act, a congressional resolution designed to limit the president's ability to initiate or escalate military actions abroad without congressional approval. Connecticut Senator Chris Murphy said the briefing confirmed his assessment that the strikes only set back Iran's program "by a handful of months," contrary to the complete destruction Trump claimed. Murphy advocated for diplomacy in addressing Iran's nuclear program, noting, "You cann ot bomb knowledge out of existence no matter how many scientists you kill." Arkansas Senator Tom Cotton expressed confidence in the "catastrophic damage" to Iran's nuclear infrastructure, highlighting the targeting of scientists, centrifuges, and conversion facilities over 12 days. Cotton stated, "That's why we're confident, since all of those are single points of failure in an effort to get a nuclear weapon, that we have had an extraordinary success." South Carolina Senator Lindsey Graham echoed the sentiment that the sites were "obliterated" but cautioned that Iran retains nuclear ambitions, stressing the ongoing nature of the problem. "I don't want people to think the problem is over, because it's not. They're going to keep trying this," he remarked. North Dakota Senator John Hoeven cited CIA assessments indicating a one to two-year recovery time for Iran's nuclear program, suggesting that the demonstration of American capabilities opens new diplomatic opportunities.
