I'd say its more of you give the "World Police" role to a country not mature enough to handle it. The British Empire did rather well in it up to the early part of the 20th century when we handed over the mantel when we bankrupted ourselves to stop Nazi tyranny.
Here you have a senile old man ordering the most ridiculous chaotic retreat and not even considering what else needed to be done for a successful evacuation. They've just handed high quality weapons to a bunch of angry barbarians who won't be afraid to use them. Just like the Zulus using British rifles in the Anglo-Zulu War once they got their hands on some.
