they were there , they overwintered - they weren't a deterrent - they were a patherttic force as the russo Japanese war a few decades later proved so you assertion that Britain and France were ready to support the south if the russ weren't there is unfounded and sheer nonsense but Britain at no stge had any intention of getting involved and never did in the slightest way - you will not be able to show they did the Brits were firmy against slavery and many Brit cotton manufacturers lost money ....but were mostly Godly men and were willing to rather than support slavery
you mentioned 100s and 100's of years where US and russia were allies - nonsense without the slightest truth
you metioned russia turning the tide of war .....when it happened it happened on land
you are just like putin .....attempting to re-write history for political purposes and dreadfully dishonest
