Yes, I think we are prepared should an Invasion from Russia takes place. We are the strongest. Sadly, however, the following other countries need to be taken seriously as well. The information below shows we 'absolutely' need to take the possibility serious.
North Korea has around 1.02 million military personnel and 73 submarines - more than Russia and the US.
Also, the nation also has access to 4,060 tanks, but only has 286 helicopters and three warships.
By contrast, the US has just 409,000 active military personnel, despite spending $611.2billion (£459.4 billion) on defence.
However, the US also commands 5,437 helicopters, 88 warships, 2,384 tanks, 71 submarines and 1,442 combat jets.
Putin's modern day military is made up of just 240,000 personnel, with a defence expenditure of $69.2billion (£46.6billion).
Russia has 2,700 tanks, 1,090 combat jets and 854 helicopters, with access to 34 warships and 62 submarines.
The Chinese army boasts 1.6 million military personnel with an estimated expenditure of $215.2billion (£161.7billion).
