Why aren't true compact trucks and SUV's offered in the US anymore?

The last true compact truck we had was the Ford Ranger and it left us in 2011. Trucks like the Toyota Tacoma, Nissan Frontier and new Chevy Colorado have grown from compacts to near full size proportions. The original Toyota 4Runner was a compact SUV, now the current 4Runner is a mammoth in comparison. The Jeep Wrangler is a giant too compared to what it was back in the 90's. So what happened to true compact 4x4 vehicles? I have a 2004 Tacoma and it is a compact (the last year before they grew even bigger), but in a few years I am going to be looking into replacing it, but I am real hesitant because I don't want a goliath 4x4 truck, I have no need for something large and prefer the compact, convenient size of a little truck. Why can't we get these types of vehicles in the US of A anymore? Other countries still have little compact 4x4 trucks and SUV's but everything just keeps getting bigger in the US, and it just doesn't make sense to me if gas prices and fuel economy standards are going to keep getting higher and tighter.
