I would take the Global FirePower rankings with a huge grain of salt. A few examples that stand out right away:
1. How is India ranked #4 ahead of Japan, France, Uk, ? All these countries have far more advanced weapons, and global firepower projection capabilities than India.
2. How is Brazil #9 ahead of Pakistan, Turkey, Egypt, Iran? There military is almost none existance and has almost 0 overseas training
3. How the hell is Israel ranked #20 with the likes of KSA and Spain ahead of it is just pure laughable. Any list that does not have Israel within top 12 minimum would not be credible. There air force of 300+ F-16Is, 50+ F-15I, and now 32 F-35 backed by powerful missiles and air defences like irondome can feasibly even face a military the size of Indias and come out on top.
1. US
2. China/Russia
3. Russia/China
4. Japan
5. UK
6. France
7. India
8. Korea
9. Pakistan
10. Israel
This is just conventional forces. Pakistan would be be ahead of of Korea/Japan as well as would other nuclear nations if nukes are to be included.
Furthermore I would not be surpised if within the next 10 years Pakistan rapidly excelerates to the 7-6th spot. Maybe I am being to optimistic but with the pace of development our military and with all the new weapons expected to come onboard compared to others on that list who are now facing huge budget cuts to the military including India.
Over the next 10 years I can make a reasonable estimate that the following nations will become more powerful and move up within the top 10... Japan and Pakistan.
Nations that I expect to rapidly fissile out in capabilities but still remain in the 10 top (potentially) include Russia, Uk, France who are all facing large budget cuts and weapon cuts.
Wildcards are India and Korea. India is facing catastrophic economic situation and political backlash with farmers protests. Things have been really bad the last few years and could rapidly decline much further for India leading to its decline in the top 10 but still remaining due to its size.
The 1 nation that a have a potential to enter the top 10 includes Turkey which has the potential to unseat Korea or Israel.
