Russian actions in Syria are considered brave, while strategy of the US is without results. Russia has taken necessary steps to completely eliminate the ISIS terrorist group.
The strategy of the US is viewed as hesitant. On the other hand, Putin decided to take some action which gives immediate results.
In addition to all this, it seems that the US wants to harmonize their actions in Syria with Russian actions. One of the reasons behind this is to eliminate the possibility of military clashes of these two countries.
According to John McLaughlin, any action taken by the US in the future will be conditioned by Russian military strategy in Syria.
Russia decided to take action in Syria, which only resulted in increased influence of Russia in the Middle East.
Russia launched air strikes at ten ISIL targets, which were successfully destroyed. While Russia is fighting terrorist groups, the US believes that Russia is specifically targeting oppositional forces in Syria backed by the US government.
It is believed that Russia wants to disgrace the US government in public. Any response given by the US is held back because the US does not want to confront Russia.
