Now emphasizing diplomacy, the Obama administration has just withdrew its cooperation with Russia over Syria wars. On the other side, Moscow suspended a key nuclear weapons treaty it had just signed with Washington more than a decade ago.

Frustrated over the relentless Russian and Syrian bombings in the city of Aleppo, the White House in Washington announced that it was breaking off bilateral talks with Russia over Syria's providence and cancelling its partnership plans to share military intelligence and resources information with Moscow, Russia.

The said decision came after the continuous negotiations, including near-daily telephone conversations between Secretary of State John F. Kerry and Russian  Foreign Minister Sergei Lavrov. Both aimed at reducing violence and opening up routes for desperately needed food and medicine for besieged enclaves.

""This is not a decision that was taken lightly, unfortunately, Russia failed to live up to its own commitments and was also either unwilling or unable to ensure Syrian regime adherence to the arrangements to which Moscow agreed." Kirby exclaimed.

The Russian government had agreed to a cease-fire last month however, that was just quick and temporary. Russia has an argument that the United States has failed in its commitment to separate the moderate rebel groups it supports from more radical factions such as the Syrian branch of Al Qaeda.

On the other side, the U.S. counters that Russia and its ally, the government of Syrian President Bashar Assad used the time to pound rebel-held portions of Aleppo. This includes numerous civilian neighborhoods with barrel bombs and other indiscriminate attacks. The result-hundreds of people have been killed during last week.

Russian President Vladimir Putin signed an act suspending Russia's participation in a treaty with the U.S. designed to eliminate nuclear weapons. 

The Russian President cited "a threat to strategic stability as a result of USA's unfriendly acts toward Russia." This was in reference to a deepening diplomatic spat between the Kremlin and the White House over Syria. Also, the tensions and sanctions that followed Russia's 2014 takeover of Crimea and its support to separatists in eastern Ukraine was a basis.

More so, Kirby said the United States will withdraw a team that had been dispatched to open a so-called joint implementation center. This is in which Russian and American armed forces were going to join efforts to fight Islamic State and other jihadi groups.
