Earlier this month, the US said it would start deploying long-range missiles in Germany from 2026 as part of a longer-term militarisation that will include SM-6, Tomahawk cruise missiles and developmental hypersonic weapons

Putin, during his speech to sailors from Russia, China, Algeria and India to mark Russian Navy Day in the former imperial capital of St Petersburg, said the US risked triggering a "Cold War-style missile crisis" with the move

"The flight time to targets on our territory of such missiles, which in the future may be equipped with nuclear warheads, will be about 10 minutes," Putin said on Sunday

"We will take mirror measures to deploy, taking into account the actions of the United States, its satellites in Europe and in other regions of the world," the Russian President added

Notably, such missiles, which can travel between 500 and 5,500 km (310-3,420 miles), were the subject of the Intermediate-Range Nuclear Forces (INF) Treaty signed by the US and the Soviet Union in 1987. But both Washington and Moscow withdrew from the arms control treaty in 2019, each accusing the other of violations, as reported by Al Jazeera

Putin, who sent his army into Ukraine in 2022, casts the war as part of a 'historic struggle' with the West, which he says humiliated Russia after the Soviet Union fell in 1991 by encroaching on what he considers Moscow's sphere of influence

On the other hand, Ukraine and the West say Putin is engaged in an "imperial-style landgrab." They have pledged to defeat Russia, which currently controls about 18 per cent of Ukraine, including Crimea, and parts of four regions in eastern Ukraine

Russia says the lands, once part of the Russian empire, are now again part of Russia and that they will "never be given back," Al Jazeera reported

Russian and US diplomats say the relations between the two countries are worse than even during the 1962 Cuban Missile Crisis. While both powers urge de-escalation, they are also accused of taking steps towards escalation
