After telling an anecdote to the 2017 Conservative Political Action Conference audience about his time serving in Afghanistan during the public announcement of the Obama-era troop withdrawals, Waltz said of the War in Afghanistan, "So, are we 15 years in? Yes. Are we in for a lot more fighting and do we need a long-term strategy to undermine the ideology of Islamic extremism—just like we did fascism and just like we did communism? Yes, we do. Uh, and you know, I think we're in for a long haul and I think our nation's leadership needs to begin telling the American people, 'I'm sorry, we don't have a choice, we're 15 years in to what is going to be a multi-generational war because we're talking about defeating an idea.' It's easy to bomb a tank, very difficult to defeat an idea and that's exactly what we have to do."
