America’s longest war isn’t ending anytime soon—in fact, it’s about to expand.

President Donald Trump’s top military advisors have put forth a plan to boost U.S. troop numbers in Afghanistan by 3,000 to 5,000, the Washington Post reported late Monday. The U.S. currently has 8,400 troops in Afghanistan.

“The definition of insanity is repeating the same strategy and expecting different results. Decades of the military approach by the U.S., NATO, and Russia and others before have never worked,” said anti-war group Peace Action. “Why would Trump want to continue wasting American blood and treasure in Afghanistan?”

“I cannot believe this is an actual headline in the 16th year of the longest war in the history of the republic,” tweeted MSNBC‘s Chris Hayes in response to the news.

The plan also empowers the Pentagon, rather than the White House, to unilaterally decide on troop numbers and how to use those troops in the battlefield.

Furthermore, it would “give the military far broader authority to use airstrikes to target Taliban militants. It would also lift Obama-era restrictions that limited the mobility of U.S. military advisers on the battlefield,” wrote the Post.

“The plan comes at the end of a sweeping policy review built around the president’s desire to reverse worsening security in Afghanistan and ‘start winning’ again, said one U.S. official, who like others spoke on the condition of anonymity to discuss internal deliberations,” the Post reported.
