Bacevich claims that conservatives have not been forthcoming about their errors in supporting the invasions of Iraq and Afghanistan, even when they make small concessions about certain features, as Max Boot and John McCain did recently. The antiwar conservative movement has a huge opportunity to use the failed war on terror as an example of just how badly interventionism and nation building can go wrong, but so far they have not mobilized large support. Similarly, the left has an opportunity to oppose President Trump on his very worst policies (the wars), but mainly have chosen to attack him for the supposed Russia scandal and his personal life. Any significant resurgence of the antiwar left would require its members to face up to their support for President Obama, one of the worst war hawks of all time. Many are unwilling to do this.
