Seriously though, I think that Russias top position at the moment is mostly due to inertia (and how well Putin uses it to be fair to him). Our military, nukes aside, is in a horrendous state — it's enormous in terms of the size (about 1 mil of military personnel), but about 300 thousands of those are mandatory drafted youngsters who don't even learn how to shoot in their one year in the army, spending most of the time painting roads and making snow sculptures. Most of the operations on foreign grounds, like Syria, are made not by the regular army, but by private contractors (like PMC Wagner)...
And today you need to invest in new technologies instead of trying to solve the issue by throwing cannon fodder at it. I wouldn't say that what the Russian army did/does in Syria & Ukraine was significantly impressive.
In terms of economy, we've also missed out on a golden opportunity that came along in the 00's — to properly invest the money from hyperinflated oil and natural gas prices back into our economy...
Anyway: Russian aggressive foreign politics are making it look like a bigger force than it actually is. US and China are completely out of the reach and I'd argue that Germany is as well. The rest is debatable depending on what exactly do you consider to be country's key attributes, but I'd say that the 5th place in the world order would be a very generous assessment, more realistically we're somewhere in the bottom of top-10.
