U.S. Considers Supplying Arms to Ukraine Forces, Officials Say

WASHINGTON — With Russian-backed separatists pressing their attacks in Ukraine, NATO’s military commander, Gen. Philip M. Breedlove, now supports providing defensive weapons and equipment to Kiev’s beleaguered forces, and an array of administration and military officials appear to be edging toward that position, American officials said Sunday.

President Obama has made no decisions on providing such lethal assistance. But after a series of striking reversals that Ukraine’s forces have suffered in recent weeks, the Obama administration is taking a fresh look at the question of military aid.

Secretary of State John Kerry, who plans to visit Kiev on Thursday, is open to new discussions about providing lethal assistance, as is Gen. Martin E. Dempsey, the chairman of the Joint Chiefs of Staff, officials said. Defense Secretary Chuck Hagel, who is leaving his post soon, backs sending defensive weapons to the Ukrainian forces.

In recent months, Susan E. Rice, Mr. Obama’s national security adviser, has resisted proposals to provide lethal assistance, several officials said. But one official who is familiar with her views insisted that Ms. Rice was now prepared to reconsider the issue.

Ukraine, the report notes, also needs reconnaissance drones, especially since the Ukrainian military has stopped all flights over eastern Ukraine because of the separatists’ use of antiaircraft missiles supplied by Russia.

The report also urged the United States to provide military communications equipment that cannot be intercepted by Russian intelligence.

Poland, the Baltic States, Canada and Britain, the report says, might also provide defensive weapons if the United States takes the lead.

The report was issued jointly by the Atlantic Council, the Brookings Institution and the Chicago Council on Global Affairs. The other officials who prepared it are Strobe Talbott, who served as deputy secretary of state in the Clinton administration; Charles F. Wald, a retired Air Force general who served as deputy commander of the United States European Command; Jan M. Lodal, a former Pentagon official; and two former ambassadors to Ukraine, John Herbst and Steven Pifer.
