You're not likely to see a proliferation of combat-capable drones as a result of the policy, but you should see them reach more than just the handful of countries that have them today. Not everyone is in favor of this expansion, of course. Critics already accuse the US of relying too heavily on drone strikes (some of which lead to civilian casualties), and there's a concern that allies buying these aggressor UAVs may do the same. Since politicians won't have to put anyone directly in harm's way, they might be more tempted to bomb targets when negotiations or sanctions would be enough.
