Or, to put it more succinctly, Iraq is occupied by the US in about the same sense that Germany is. And while the US no doubt exerts influence over Germany in part via its military power, I think the position that the US military presence in Germany is part of a “land grab” would be a rather fringe one.

It depends where you're sat and when. It's almost certainly a fringe perspective in the US, because I don't believe American's really think about it that much.

Whether troop presence is viewed as occupation or not in each of the >50 [1] countries currently "hosting" troops is very much a matter of personal perspective, the fringeness of which will vary from country to country.

I don't believe that it really changes the fact that yes, US troops occupy the UK, Germany and Iraq, and many more. The most substantial deployments, e.g., Germany, Japan, South Korea, and until recently Iraq and Afghanistan, were very much the product of invasions. At the time of those invasions, many of those on the receiving end would have very much felt on the receiving end of a land grab. It's just their grandchildren have been conditioned to view this state of affairs as natural.

The general pattern is "bomb the bejesus" [2] out of a country. Plant base. Install a friendly government and ensure a favourable operating environment for US interests. The UK is an exception in that it wasn't bombed by the US, but the upshot is the same. We're a wholely-owned subsidiary of corporate America, and a giant aircraft carrier on the other side of the Atlantic -- as the US's latest adventure in Iran has clearly demonstrated.

You may quibble over the "land" in land-grab, but the strategic bits (e.g., oil fields, bases) are very much owned, and the territory as a whole controlled by pliant governments.
