Regarding economy well here is a little history lesson
1.Battle of Badr Quraiysh big economy big power big army vs Muslims of Medina small army small economy and lack of resources guess who came out victorious.
2. Muslim VS Persians
Persians were super power and Muslims with smaller army smaller economy overcame them
3. Muslims vs Roman's
Romans big advanced army big economy vs muslims smaller economy outdated military compare to Romans well guess what was the result?
4. Mongols vs Calphiate of Baghdad
Mongols with no economy defeated the super power of the world why because better economy made super power lazy too lazy to self defend.
5 . Ww2 Germny smaller economy smaller army kicks *** of combined army of three counties Britian France and Belgium.
6. Vietnam Vs USA
US big enonmy nuclear power most advanced army on the planet vs Viet cong and army of third world country guess who won?
7. Afghanistan VS Soviet Union
Soviet Union another super power of the time vs rag tag soldiers in Afghanistan with no economy guess who came out victorious.
And then recent events of Afghanistan as well.
So these lectures about better economy before starting a war is a myth just a myth. It's a day dream that Indians have fed you because its they who talk about big economy = winner in actual war.
1. The only battle in history in which Allah Almighty intervened (i.e. thousands of angels dispatched to help Muslims). Even in this battle, Muslims had done their homework - they reached and took over the only pool of water in the region, and when enemies reached the spot, they broke ranks and rushed towards the pool of water only to be bombarded with arrows in the process.
2.
The Persian Empire and
The Byzantine Empire were fighting a lengthy war, and it took a heavy toll on the strength and economy of both by its end. Through all these years, Holy Prophet (PBUH) worked very hard to establish the order of Islamic brotherhood by converting and uniting various tribes in the region earlier; organization, strength, discipline, and motivation of this force had no peer. No wonder this force crushed the already battered Persian Empire in a war.
3. See above.
4. Mongols with no economy? LMAO! Joke of the century.
Prior to Genghis Khan, Mongols were just like ancient Arabs - primitive and warring. But Genghis Khan changed everything; he realized that in order to transform Mongols into world's greatest power, he will have to put his house in order (silence those who kept them apart) and push for reforms in all aspects of life (economic + military).

5. When it came to fighting wars, much of Europe was stuck in the ways of WW1 at the time (i.e. Maginot Line being a byproduct) but Germany had evolved as a society and innovated in the art of warfare in comparison.
Beautifully summarized here:
France suffered a notoriously quick defeat at the hands of its German neighbor in World War II.
The country capitulated just six weeks after Hitler's land invasion began on May 10, 1940.
France had a system of defense, built in the more than ten years leading up to 1939, but it failed miserably.
The problem was that Maginot Line, a great line of fortifications that spanned France's borders with several neighbors, was essentially a glorified trench.
And like any trench, it belonged to the age of the First World War, not the mechanized warfare known as blitzkrieg that Hitler brought to the Second.
The Wehrmacht simply went around the line, borrowing the low plains of Belgium to France's north.

6. This war was unpopular in US and racial tensions within had a profound impact on the organization and cohesion of American troops in Vietnam on top. Additionally, Vietnam have a terrain which does not favor open-ended mechanized thrusts in numerous sectors, and the Vietcong were receiving all mamner of assistance from USSR and China during the course of war. Conversely, Americans were supporting South Vietnamese who proved incapable in governing/uniting Vietnam over the course of years. Under these circumstances, US could not win this war.
7. USSR was a mere shadow of its formerself at this stage -
poor economy and
Perestroika began to unhinge Soviet Socialist Republics (SSR) who were bind together by forces of communism otherwise. Due to these factors, USSR could not station a massive force in Afghanistan, and chose to entangle itself in largely dysfunctional Afghan politics instead (Communist versus Socio-Religious). Conversely, US and Pakistan offered all manner of assistance to the so-called Afghan Mujahideen and also encouraged many more to wage jihad against forces of communism in Afghanistan (i.e. Operation Cyclone - a brainchild of CIA). Consequently, USSR was not in the position to do much in Afghanistan. However, this war destroyed Afghanistan.
HISTORY is not your forte it seems.
Lessons to consider?
1.1.) Put your house in order first and foremost
1.2.) Devise a strategy to fight a war
1.3.) Innovation in the art of warfare (potential surprises for the enemy)
1.4.) Have powerful allies and/or support structures on your side - extremely important consideration
Where do you see Pakistan at present, in the light of the above?
