I'll single out quotes that are worrisome.

On technology:

[quote][b]although a renewed focus on technology[/b] allowed Poland to eventually recover and reach a state of economic growth[/quote]

[quote]Despite what the name may imply, the company also oftentimes [b]funds research into various technologies[/b], and maintains strong relations with major Polish universities like the [b]Warsaw University of Technology[/b], Jagiellonian University, and the University of Wroclaw.[/quote]

As for military build-up - The issue is that you still made no mention of the problems Czechoslovakia and Ukraine's annexation should be giving you. Not just economically straining, but in terms of nationalism and the dissent that is probably prevalent from some groups there, who want independence or more autonomy. Some of these groups will try to gain those things politically, and some will be violent. Either way, it would be a big problem for Poland that is worth mentioning. You didn't mention it, and the closest thing to it is your mentioning of a military build-up to "strengthen Poland's position". While it's arguable that Poland would want to build-up its military out of fear of Germany and the instability in Russia, it sort of comes off as you using the unrest within Poland itself to justify a military build-up. It would sound less like that if you addressed the problem in the sheet and mentioned what Poland has been doing to quell it, not just militarily but politically.
