But the Russian leader will be fully aware of the magnitude of the threat posed by long-range missiles supplied by the West.

The Institute for the Study of War, a think tank, published a map of 225 Russian military installations within ATACMS range.

Former US envoy to Ukraine Kurt Volker said Biden’s decision would allow Ukraine “to go after airports, ammunition depots, fuel supplies and logistics that Russia has, which are currently in a sanctuary zone in Russia.”

Volker told the BBC that Biden’s decision would cause Russia to act more cautiously.

Rejecting Putin’s threats, Putin said that the Russian leader “should have foreseen that Ukraine will make efforts to respond.”

Ukraine has had ATACMS with a similar range for a while, as well as Storm Shadow missiles from the UK and France, but their numbers are unknown. However, they were not allowed to be used in Russia.

France and the UK are expected to follow the US’s lead and give the same authority to Ukraine. They have not commented so far.

White House officials emphasize to US media that Biden’s change of heart is in response to Russia’s deployment of North Korean troops; This is a signal to Pyongyang not to send more troops.

This comes after Ukraine has come under attack from Russia in recent days.

In the attack on Odessa on Monday, 10 people, including seven police officers, died and 47 people were injured.
