Having been involved in the direct US efforts to help fight the drug problems there and in other countries, I call BULLSHIT on your dishonest accusations.
The PI has massive corruption problems,
The US has a vested interest in stopping drug production and distribution before it reaches the US.
We've invested millions in funding and resources as well as provided professional law enforcement and military training and assistance.
If the problem persists, it is NOT for lack of our efforts. It's a problem of fighting an uphill battle with some members of the PI law enforcement actively working against those efforts.
But, in your narrow view, their drug problem is our fault because we didn't solve it for them?

I am so glad you posted the above.
According to your personal experience, you are aware of the mass corruption problem the Philippines has had for decades, due to the crime syndicates and drug lords that operate within their nation. However, if you have known this for some time, the US has to have also known about this situation as well. Consequently, the facts you shared bolsters my accusation that not only the US did not strategically help the Philippines combat the runaway crime in their country, but also contributed to it.
What strategic ally would willingly provide, "millions of funding and resources", as quoted by you, to a government they know would line their own pockets; thereby, allowing the law and order of the Philippines to deteriorate?
The US IS NOT STUPID!
Despite knowing that their money was not being used to better the situation in the Philippines, the US has nevertheless continued to provide financial aid to the corrupt government of the Philippines all these years because
ALL THEY CARED ABOUT WAS THEIR MILITARY AGREEMENTS WITH THE PHILIPPINES THAT ALLOWED THEM TO CONTINUE THEIR HEGEMONIC STRATEGY TO CONTAIN CHINA!The US does not care in the least of the social and economic well-being of the Filipinos and that is why Duterte has decided to look for support from other countries that understands what the Philippines really needs.
