And that's great. But that's not really the threshold for "making a difference." Obviously everyone is glad you did that. But it didn't change the status quo, it didn't move the ball forward towards worldwide stability, and it certainly won't be considered as historically significant.
Again, I'm glad I served. But the organization I served in, and the strategic objectives of that organization don't seem to have done... anything. Or with a more cynical perspective, made things worse. And I 100% blame the political leadership for that. It's not about blame, just results. And I'm not sure I see what was accomplished by OEF/OIF/OFS/OIR, other than the first few months of annihilating the Taliban as revenge.
I enjoyed serving. But I didn't make the world a better/safer place in the long run because those in charge failed to use our efforts effectively (or with any particular goal in mind). Afghanistan is still run by the Taliban, with newer, better weapons and equipment. Saddam is gone, and Iraq is a bigger mess. Libya is a mess. Tunisia, meh. Iran is still exporting terror and chaos all over the Middle East. Pakistan is still a shitty ally. Syria is more of an enemy than before. Turkey is belligerent to any Western interests, but can fuck up NATO votes. Islamic extremism has spread through more of the West than when 9/11 happened. And all of that added to a catastrophic debt situation.
Tactically, I agree. But a huge amount of the threats we neutralized were threats directly related to our presence. That's not to say we were at fault and caused the threats by being there, but it was still a self-fueling war.
I'm not mad about it. I just see an organization that has resoundingly failed at every major endeavor (again, strategic level, not warfighter level) and yet those who led us through failure have never been held to account. It should surprise no one that an organization with no real goal, no real accountability, and no remaining identity (modern-day DOD) would create and attract the types of leaders we talk about here every day.
This is not what successful organizations look like.
