Hey, objectively if it weren't for the Russians we'd be speaking German all over Europe... doesn't mean you have to agree with everything that
Putin does (I sure as hell don't!)
Similarly, we owe the US a great deal in keeping us from all speaking
Russian in Europe! And relatively safe from ISIL in the present. But that doesn't mean we have to be happy with the arrogant imperialist attitudes their administrations are often guilty of (Iraqi invasion to name but a recent example).
To get back on topic, would a US company allow a foreigner with a green card to return to his country every time he was called up for reservist duty? (not a rhetorical question, I really don't know)
How would a US corporation react if a foreign tax service demanded that the names of all their citizens in the employ of that corporation be turned over to said foreign tax authority, and that from now on a portion of their paycheck be witheld for tax?
