Who contributes the most to the coalition against Islamic State?

The United States State Department currently lists more than 60 nations as members of the "Global Coalition to Degrade and Defeat ISIL."

While many countries have pledged military or humanitarian support, the State Department indicates that simply "exposing ISIL's true nature" can qualify a nation for inclusion in the coalition.

The table below, compiled by Foreign Policy, tracks major developments in commitments by coalition partners, including the date of the first strikes by each country involved in the air campaign and the most recently announced totals for military and humanitarian aid contributed by the various partners.
