The Russian government is doing the same thing over and over again and expecting different results. The Russian government keeps making agreements with Washington, and Washington keeps breaking them.
This latest exercise in what Einstein defined as insanity is the latest Syrian cease fire agreement. Washington broke the agreement by sending the US Air Force to bomb Syrian troop positions, killing 62 Syrian soldiers and wounding 100, thus clearing the way for ISIS to renew the attack.
Russia caught Washington off guard in September 2015 when the Russian Air Force was sent to bomb ISIS positions in Syria, thus enabling the Syrian Army to regain the initiative. Russia had the war against ISIS won, but pulled out unexpectedly before the job was done. This allowed the US or its agents to resupply ISIS, which renewed the attack.
So Russia had to return to Syria. In the interval Washington had inserted itself. Now the Russian air attacks on ISIS are more complicated, as is the sky over Syria. Russia notifies Washington of its planned attacks on ISIS, and Washington warns ISIS and perhaps Turkey which shot down a Russian plane. Nevertheless, the Syrian Army gained ground.
But each time victory was stymied by “peace talks” or a “cease fire,” during which the US supported forces would regroup. Consequently, a war that Russia and Syria could have already won continues, and with a new element. Now Washington has directly attacked the Syrian army.
