Take Putin's nuclear changes with pinch of salt, expert sayspublished at 08:37 Greenwich Mean Time
Dr Eleanor Bindman, a senior lecturer at Manchester Metropolitan University and expert in Russian politics, spoke to our colleagues at 91热爆 Radio 5 Live this morning about developments between Russia, Ukraine and the US over the last few days.
Asked about Washington's decision to allow Ukraine to fire long-range US missiles into Russia, and give Ukraine anti-personnel land mines, Bindman says that where escalation has happened, "it has always come from the Russian side first".
"In a sense, Ukraine鈥檚 Western allies are responding to that escalation rather than initiating it," she adds.
On changes to Russia's nuclear doctrine, Bindman says that Putin has made nuclear threats before, and that the latest decision should be "taken with a pinch of salt".
"A lot of it is about using this escalatory rhetoric without necessarily acting on it," she says.
