60's Cold War Soviet Russian Theme ?? *spoiler*

I watched this for the first time last night, at first I was thinking wow, this movie looks like it's gonna be pretty darned good.. Ok, some of the stunts, fx and dialogue was very amateur and cheap, but I was intrigued by all the Soviet Cold War style surroundings going on, like the Soviet Style Propaganda type 'Love ya Motherland' type Posters on the Walls in the NSA offices, the commy soviet style uniforms, the drabby greyness decor, the clunky 60's Russian'esque knobs and switches on computer terminals, the old 50's and 60's style Russian Cars with Russian plates.. Im assuming it was all meant to be taking place in the US, but why all the Cold War era Soviet theme.. I was eagherly waiting for some sort of explanation to all this stuff, more so than the actual outcome of the vampire story going on. I was thinking, are we gonna be informed that at some point in the Past the Soviets conquered the United States, and thus some technologies and styles remained Cold War era style.. What was it all about? The movie ends, but, it never got explained, wahhhhh, what a shame... Such a waste of an interesting sub story, an opportunity missed if you ask me...

Any thoughts anybody? Or, were we not meant to think about all that stuff and simply be satisfied with the dodgy low budget Vampire escapade..???
