Russia and the United States warships recently again friction. Russia said it had driven away a US destroyer entering Russia’s territorial waters, while the US said it was sailing in international waters and had not been expelled from any country’s territorial waters. < / P > < p > recently, the US government officially withdrew from the open sky treaty, while taking a negative attitude towards the renewal of the new strategic arms reduction treaty, and also had friction with Russia at sea. This series of actions reflects the trend of intensified Military game between the two countries. Russian and us analysts all believe that from the standpoint of US President elect Biden and his team, the future of Russia US relations that continue to hover at the freezing point is not optimistic. Russia’s defense ministry said on the 24th that the US Navy Destroyer “John McCain” entered the waters near Peter’s Bay in Russian territorial waters on the same day and crossed the Russian territorial sea line “two kilometers”. Russian anti submarine Destroyer “admiral Vinogradov” issued a warning to the “John McCain” and said it might collide with it. “John McCain” immediately left Russian territorial waters. < / P > < p > the seventh fleet of the US Navy said in a statement on the 24th that the “John McCain” is carrying out “operation freedom of navigation” in international waters and has not been expelled from the territorial waters of any country. U.S. media said the U.S. Navy’s operation in Pete’s Bay is very rare. < / P > < p > General Kravchenko, former chief of the general staff of the Russian navy, believed that the “John McCain” was obviously conducting reconnaissance activities. The president of Russia’s Institute of geopolitics, Mr. sivkov, said that the “John McCain” may try to induce Russia to attack and aim at it, so as to spy on the operation of Russian ships. < / P > < p > in recent years, there have been constant friction between the Russian and American armies. Two military vehicles collided in northeastern Syria in August, injuring four US personnel. In December 2018, the US Navy Destroyer “maccampbell” sailed into the waters near the Gulf of Peter the great in Russia, which Russia said was “provocative and demonstrative”. < / P > < p > the military friction reflects the tense situation of Russia US relations. Since US President Trump came to power, the relationship between the two countries has been at a deadlock. According to Russian officials, the current Russian US relations are at the lowest point in history, and the high-level dialogue between the two sides has in fact been interrupted. < / P > < p > kortunov, director of the Russian Council for international affairs, a think tank, said that Trump’s commitment to repair bilateral relations has never been fulfilled, and the four years since 2016 have witnessed a sharp deterioration of Russian US relations. On the 22nd of this month, the US government announced its formal withdrawal from the open sky treaty, which is signed by the US, Russia and most NATO countries. Since the 1970s, the arms control treaty has been the core pillar of us Soviet and US Russian relations, and the open sky treaty is a successful case of “cooperative monitoring” in the field of arms control. The US withdrawal from the treaty is seen as another blow to the already fragile US Russian relationship. < / P > < p > as the U.S. government is about to change, U.S. and Russian analysts expect that the relationship between the two countries will still be difficult to improve in the future. U.S. analysts generally believe that President elect Biden will take a tough stance on Russia after he takes office, and the tense relations between the two countries will continue. Biden himself said in an interview with CBS in October that Russia’s destruction of the U.S. security and alliance system is the current “biggest threat” to the United States. < / P > < p > Anthony brinkin, the candidate for secretary of state announced by Biden, has repeatedly criticized trump for being “too weak” towards Putin and advocated taking a tough stance against Russia; Jack Sullivan, the candidate for National Security Affairs announced by Biden, once supported the provision of anti tank missiles to Ukraine in response to Russia in the Ukraine crisis. < / P > < p > Russian officials and scholars are not optimistic about the trend of Russia US relations after Biden came to power. Slotsky, chairman of the International Affairs Committee of the Russian State Duma, believes that the relations between Russia and the United States will not improve after Biden takes office, because it will be those who have worked for the Obama administration who will decide the foreign policy of the United States at that time and regard Russia as the enemy of the United States. < p > < p > Ivanov, former Russian foreign minister, said that many people in Russia are worried that Biden may take a stronger stand against Russia and expand the already severe sanctions against Russia.
