WASHINGTON — As Ukrainian leaders warned on Monday of “a great war” with Russia, NATO leaders meeting in Wales this week were expected to endorse their most concrete response yet to increased Russian military intervention in Ukraine: establishing a rapid-reaction force capable of deploying quickly to Eastern Europe, officials of the alliance said.

The new force of some 4,000 troops, capable of moving on 48 hours’ notice, will be supported with logistics and equipment pre-positioned in Eastern European countries closer to Russia, with an upgraded schedule of military exercises and deployments that are intended to make NATO’s commitment of collective defense more credible and enhance its deterrence.
We need to use Russian actions as a clear message to all of Eastern Europe(Finland, Sweden, Georgia, etc) that joining NATO is the only means to ensure their security.
