which are the top five most powerful countries ?

@Subsumedpat I can agree on the 4 u mentioned but was reading somwhere .... uk's army strength is not that good even if compared with india https://www.quora.com/What-if-the-United-Kingdom-and-India-went-to-war

@scottamadore2 I thought about India as they on paper quite powerful but I tried to consider all factors. In a war I think the UK could ramp things up quite quickly and the country as a whole has a resolve the Indian's could not match.

@Subsumedpat I am not supporting any country here ... but I am bit confused seeing uk in the list that is why I mentioned india becaise uk lacks almost 5-10 times in everything in regard of weapons ,navy aircrafts and on field India has 2nd largest army in world.
wonder!!! this country once ruled india for more den 200 years lol

@scottamadore2 When you look at how they stood up to Hitler in WW2 I think you understand the why. The whole country comes together for total maximum effort something you will not see in India.

@Subsumedpat if u are talking about ww2 ... it was not Uk alone that was ALliance b/w uk us australia and other europen nations so it was not the effort of whole country ... and uk is not speniding much on R&d for army compared to other countries
A country like this has only 1 aircraft carrier, 4 corvette warships battle tank 407 where as india has2-3 carriers 36 corvette warships and 6464 battle tanks and list goes on ... I am not talking about theory here but real statistics

@scottamadore2 But the war started in 1939 and the US did not come in until 1941, Europe fell except for the UK.

@Subsumedpat exactly it was 1939-41 almost 60-70 years back ... everything has changed since that time If u remember India was colony of British empire during ww2 and large number of the soldiers from east India company were sent for ww2 from India .
