Surely, you understand why they did this? There is a perfectly good rationale for running these kind of operations. It's just that you're miffed about the fact that you're not able to do anything about it.
So if you're part of some impotent government that does not know how to, or wants to project power, instantly you're at the mercy of institutions of governments that can. No amount of tree-hugging or moral high ground is going to save you from extinction.
And it's not all that bad. It's mostly power-play and politics really.

"Once you set up a covert operation to supply arms and money, it's very difficult to separate it from the kind of people who are involved
Do you claim to understand why the Reagan administration "did this" operation which eventually came to be known as Iran-Contra? If so, then you can explain how "blocking the fall of [soviet] dominoes" directly correlates to the distribution of drugs in specific Black-American communities. You can in hindsight claim to agree with the end goal of "blocking Communism" however, in hindsight, you would be lambasted as failing to see through the Administration's propaganda. Still claiming to support the means to that end, squarely puts you in the realm of the Abusers of Power. Abuse because the voting population never had any chance to understand what was being done in their name. This is the cycle of Power Abuse which has many in the world turned against the US (and increasingly its people not just government). As long as the (secret) three-letter agencies conduct (secret) operations using (secret) means and continue to be governed with (secret) mandates driven by an administration's (secret) beliefs without Transparent and Democratic oversight this trend will continue until its logical conclusion. Sadly.
