Although the Trump administration has voiced a desire to extract themselves from the existing military engagements in Iraq, Syria, and Afghanistan, they have not yet done so. (As a side note, the previous administration also expressed a similar desire). Thus it is perhaps premature to claim that the current administration has 'ended' the policy.

However, this misses the point that the goal of the proposed institute is to:

> ... promote an approach to the world based on diplomacy and restraint rather than threats, sanctions, and bombing.

Unfortunately, the current negotiation tactics being pursued against, say, Iran, do not fall under this new style of diplomacy. I'm sure other examples may come to mind.
