Putin says us will shed 755 diplomatic staff
You're referring to the recent diplomatic row between Russia and the United States.
On December 29, 2020, Russian President Vladimir Putin announced that Russia would be expelling 755 American diplomats and staff from the United States Embassy in Moscow, in response to new sanctions imposed by the US government.
The sanctions were imposed in response to Russia's alleged interference in the 2020 US presidential election, as well as its actions in Ukraine and other countries. The US government had previously expelled 60 Russian diplomats in response to the poisoning of a former Russian spy in the UK, which was attributed to Russia.
Putin's announcement was seen as a significant escalation of the diplomatic tensions between the two countries, and marked a low point in the relationship between the US and Russia. The move was widely seen as a retaliatory measure, and was met with criticism from many in the US and around the world.
It's worth noting that the US had previously expelled 60 Russian diplomats in response to the poisoning of the former Russian spy, and had also imposed sanctions on several Russian individuals and entities. The US government had also accused Russia of interfering in the 2020 US presidential election, and had imposed sanctions on Russia in response to its actions in Ukraine and other countries.
Overall, the diplomatic row between the US and Russia is a complex and multifaceted issue, and it's difficult to say exactly what the long-term implications will be. However, it's clear that the relationship between the two countries is currently strained, and that there are significant tensions between them.
