The Russian Embassy in the UK has come up with an odd response to the British Foreign Secretary’s decision not to travel to Moscow, citing “recent developments in Syria.” Boris Johnson’s he last-minute cancellation has been described as “absurd” by the Russian Foreign Ministry which inspired the Russian diplomatic mission in London to play some Tchaikovsky. The tune they chose to announce on twitter is a patriotic Russian war song that’s obviously meant to deliver an ominous message.

The Russian embassy shared a bit of the famous “1812 Overture” by the great Russian composer, written to commemorate Russia’s victory over Napoleon’s army in the Patriotic War of 1812. The triumphant piece is often played at various outdoor events, especially during fireworks, having become a popular reference to the milestone event both in Europe and in the US.

The UK diplomat called off his trip to Russia, saying he’d rather meet with his G7 counterparts and discuss Moscow’s stance on the Syrian issue.

Johnson, who was due to have a business lunch with Russian Foreign Minister Sergey Lavrov, and then hold a joint press conference on Monday, said his decision not to go was backed by US Secretary of State Rex Tillerson.

This could be the beginning of a potential war with Russia in Syria. The US missile strike on Assad’s top airbase has forced the hand of Vladimir Putin in Syria. Either the US and Russia come up with a mutual agreement to stop the civil war and restrain Assad, or we will surely get dragged into a war neither side wants.
