DEBKAfile's military sources report Moscow's planned retaliation for America's missile interceptors in Poland and US-Israeli military aid to Georgia may come in the form of installing Iskandar surface missiles in Syria and its Baltic enclave of Kaliningrad.

Russian Baltic and Middle East warships, submarines and long-range bombers may be armed with nuclear warheads, according to Sunday newspapers in Europe.

In Georgia, Russian troops and tanks advanced to within 30 km of Tbilisi Saturday, Aug. 15. A Russian general said Sunday they had started pulling out after president Dimitry Medvedev signed the ceasefire agreement with Georgia and president George W. Bush called again for an immediate withdrawal.

After routing Georgia over the breakaway enclaves of South Ossetia and Abkhazia, Moscow appears to be eying Poland, the Middle East, and possibly Ukraine, as the main arenas for its reprisals.

One plan on the table in Moscow, DEBKAfile's sources report, is the establishment of big Russian military, naval and air bases in Syria and the release of advanced weapons systems withheld until now to Iran (the S-300 air-missile defense system) and Syria (the nuclear-capable 200 km-range Iskandar surface missile).
