Obviously Putin's patterns of conduct over the past few years are bad for the U.S. Instead of allying with us against the Islamist threat, he is doing the opposite, encouraging Iran, Syria, and others to make trouble.
The question is, whether Putin's adventurism and expansionism, and what is clearly a dream of creating a new Soviet Union, is in the interests of Russia.
I think not. The basic threat to Russia is from China (longer range and only potential) and Islam (direct and actual). Added to that is the demographic factor. Russia is committing demographic suicide, which can only end in the same way as it is likely to end in Europe--with the Muslims moving in.
The first thing Russia needs to do is to put its house in order. They need a solid economy, solid and productive jobs for the people, a return to family values, and a reduction in mafia-style corruption. A rebirth of Christianity in the Orthodox Church and perhaps reasonable tolerance of other Christian churches would be most helpful, because Christianity provides a moral basis for people to behave themselves, instead of having to rely on the police to make them behave.
Obviously Russia wants to keep the US out of its neighborhood, and to exert some degree of control over its neighbors, but that would best be done through trade and friendship, not through force and subversion.
If Europe collapses into Eurabia, Russia will not be in a good position, and will certainly find the U.S. a more useful ally than China and Iran.
Even the Chinese have trouble with their islamic insurgencies...
