U.S. military frets over future U.S.-Russian ties

By David Morgan

WASHINGTON (Reuters) - Russia's invasion of Georgia has raised concerns among senior Pentagon officials about long-term U.S.-Russian relations, including future military ties, the top U.S. military official said on Thursday.

Adm. Mike Mullen, chairman of the Joint Chiefs of Staff, also said Russian and U.S. military officials were working carefully to coordinate the movements of their navies in an increasingly crowded Black Sea region to avoid any potential for direct confrontation.

"The message that has come from the Russians is one that is tied to invading another country, invading sovereign territory," Mullen told reporters at a Pentagon briefing.

That "has a lot of us concerned about what it means now, what it means a year from now, what it means long term with our relationship on the military-military side as well as the relationship between our two countries," he added.

Mullen offered no specifics. But Pentagon officials said before the invasion that they would pursue closer U.S.-Russian military and security cooperation in an effort to encourage constructive behaviour by Moscow in the international arena.

Russian troops and tanks poured into Georgia on August 8 to protect ethnic Russians in the breakaway enclaves of South Ossetia and Abkhazia.

Moscow has since defied pressure from the United States and European powers to withdraw from Georgia. Escalating tension has prompted Moscow to pull back from cooperation with NATO and to recognize Georgia's two rebel regions as independent states.

An increasing Western naval presence in the Black Sea in recent days further heightened sensitivities.
