INSTANT VIEW: Reaction to U.S.-Russia summit

MOSCOW (Reuters) - The following are analysts' comments on agreements reached on Monday between U.S. President Barack Obama and Russian President Dmitry Medvedev.

"I think the nuclear missile announcement is a good beginning. It gives some impulse to the negotiators to continue with the text. Both presidents want it and both of them need it, that's the important thing, but resetting relations will be a long process that cannot be done in a single day.

"The move on Afghanistan is very significant. We know Afghanistan very well, we were there, it's important we halt the flow of drugs we get from there."

"This is very positive and it's been achieved very rapidly. It's a very good start -- it's about a third of the arsenals and also includes delivery systems, which is something that the Russians were very keen to have included. Obviously, we'd like it to go further, but it's a very good start.

"One area where we'd like to see further progress is around the thorny issue of missile defense as well, but it looks like there is more to discuss there.

"I think the changed attitude by the U.S. administration (allowed this to happen)... President Obama seems genuinely to have a commitment in the direction (of nuclear disarmament) and it is obviously mirrored by Medvedev. It's the first time that Russia has said that it agrees with the goal of global abolition, which is very significant."
