The diplomatic tensions between the United States and Russia have been escalating in recent weeks, with Moscow suspending a nuclear arms treaty with the U.S. and President Putin issuing a nuclear warning to the country.

The conflict in Ukraine has been a major source of friction between the two countries, and the situation is only getting worse. Moscow recently cancelled a decree that underpinned Moldova’s sovereignty in the separatist conflict, and President Putin has threatened to resume weapons tests.

In response, President Biden has issued a stern warning to Moscow, calling for an end to the conflict in Ukraine. He has also called for the renewal of the New START nuclear arms treaty, which is set to expire in February 2021.

The situation in Ukraine is a complex one, and it remains to be seen how the U.S. and Russia will resolve their differences. For now, the international community is waiting for a breakthrough in the negotiations.
