The Financial Times mentions an Atlantic Council report on Ukraine focusing on what types of military assistance the United States and NATO countries should be providing to Ukraine:
The question is how to increase those costs for Mr Putin. The answer is provided in a report to be published next week by a group of organisations including the Chicago Council on Global Affairs (where I am based), as well as the Atlantic Council and the Brookings Institution. It has been written by a group of former US diplomats and military officers — including Strobe Talbott, former deputy secretary of state; Adm James Stavridis, former Nato Supreme Allied Commander, Europe; Michèle Flournoy, former undersecretary of defence; former ambassadors to Nato and Ukraine (including me, John Herbst and Steve Pifer); and Jan Lodal and Gen Chuck Wald, former senior defence officials.
