Their money is losing it's value , they're invading another country , flying bombers / fighters around neighboring coast lines and having nuclear readiness drills , nothing to see folks , move along .
You do realize the Ruble losing value helps Putin?
With 92% of the budget from oil sales to Europe priced in dollars,a falling Ruble helps not hurts Russia(at least to a point).It would be the same as raising the price of oil by the same % as the Rubble drops.It fills the budget gaps left since the fall in price of oil.It may even be deliberate by Russia's central bank.The main concern would be keeping inflation in check,which they have almost 500 billion in foreign currency reserves to defend the Rubble if needed.
As far as flying bombers and fighters around,the USA does that as well on a regular basis.We do not have any borders in the south China sea that I am aware of,but our aircraft have been intercepted by China at least 5 times this year.The US also conducted our largest Nuclear weapons drill this year May 12-16 (U.S. Conducts Nuclear Response Exercises - Defense One).
As for Russia invading Ukraine when NATO or the UN publicly state and show Russia has moved armor or is invading I will think something of it.Until then I am not buying it.Kiev has claimed Russia has invaded for over 7 months now almost on a daily basis,and today is no different than the last time they claimed Russian tanks entered(only last time is was 6 tanks with pictures and a Youtube video later disproved as west of Kiev by the road sign of a car dealership in the video).Things like confirmed by a NATO official mean nothing,until a NATO official actually comes out and confirms it as true.Russia has 15,000+ tanks...and they are going to invade with 30?
