Who would dare befriend us

So right now we are allegedly fighting the evil Taliban and their supporters who reside in Afghanistan and Pakistan. Yet we built these terror groups decades ago. We trained Osama and his crew in Afghanistan and we set up networks in Pakistan to sneak in money and weapons to Osama in Afghanistan. And here we are 30 years later fighting and destroying the same networks we once built. So my thought is why would anyone want to help us when there is a good chance you will be our next enemy in 30 years? If Osama only knew than what he knows now, no what i mean.
