Former NSA director Michael Hayden commented on Presisdent Trump's success bringing China and Russia to the table to sanction North Korea over its nuclear missile program.
"After many years of failure, countries are coming together to finally address the dangers posed by North Korea. We must be tough & decisive!," Trump wrote in a post on Twitter.
"Frankly the Obama administration deserves from fair criticism for their policy of strategic patience," Hayden said. "Which was frankly paying this problem forward - not solving it on their watch and passing it forward to the Trump administration."
"Sanctions are slow-moving -- they're like rust as opposed to an explosion, which are identical chemical reactions, but one obviously takes a lot more time," he noted. "The Trump team deserves some credit for getting these sanctions.
He said the sanctions are "very tough" and remarkably have the support of Russia and China: "They've got the Russians on their side and they got the Chinese to agree to them as well. This will be a slow-moving mechanism."
