Because in order to say "No" to the US empire and become an obsticle in their nefarious interests, you have to be Politically strong and self-sufficient economically AND military, more of a small power house strong enough to defend itself.
We learn from examples of Iraq and Afghanistan, both of whom opposed the US, look what happened to them.
Look at big countries like India, even despite of being economic power houses but lacking militarily and political strength, they still cave in to the US pressure greatly.
Once we have like 1000 modern fighter jets, ballistic missiles reaching every corner of earth, naval warships and fleets of submarines, and a strong economy (GDP surpasses at least a Trillion USD), we will begin to develop a strong political backbone on the world stage.
I expect this within the next 2 decades, we will see a great paradigm shift in our favours. insha'Allah
