London  - This summer's conflict between Russia and Georgia should lead to a "more considered analysis" of NATO enlargement to avoid eastward expansion becoming a "game of Russian roulette," a leading defence research institute warned Thursday.

The London-based International Institute for Strategic Studies (IISS) said the conflict had marked the "distinct end of the romantic phase of the post-Cold War order" and cast doubt on whether Georgia would be a "responsible member" of the NATO alliance.

Stockholm - The Swedish cabinet Thursday approved to provide civilian observers and other personnel to support a European Union ceasefire mission to Georgia.

The Swedish contribution would number some 25 personnel to staff a field office, a government statement said.

"The Swedish contribution of personnel and equipment is an expression of Sweden's commitment to peace and security in the southern Caucasus," the ministers for defence, justice and international development cooperation said in a joint statement.

The exact division of observers and other staff was yet to be decided, officials told Deutsche Presse-Agentur dpa.

Brussels - European Commission President Jose Manuel Barroso on Wednesday said the European Union may resume talks on a cooperation agreement with Russia, even if Moscow maintains a military presence in Georgia's separatist regions of South Ossetia and Abkhazia.

Moscow - President Dmitry Medvedev on Wednesday pledged military protection for Georgia's regions of Abkhazia and South Ossetia as he signed a partnership accord with the governments of both breakaway provinces.

"We will give each other all necessary support, including military support," Medvedev said in language formalized in the text of the agreements.

"With a view of safety of the signatories ... each party will give the other the right to build, utilize and modernize military infrastructure and army bases on its territory," Russian news agencies quoted the agreement as saying.

Berlin - German Foreign Minister Frank-Walter Steinmeier hit out Wednesday the critics of the six-point European Union peace plan for the Georgia-Russia conflict.

"I find it a bit shabby the way it is being disparaged," said Steinmeier during a debate in the Bundestag parliament.

He praised France's President Nicolas Sarkozy, who had negotiated the plan in "difficult" talks in Moscow and Tbilisi.

"This conflict and people's deaths in the southern Caucasus ended because the European Union took up the case," said the minister.
