Well it’s not racist because the standard isn’t every Chinese American, it’s every person who has relatives in a foreign country. You are incorrectly staying what the policy would be to make your point (because even though this story is about Chinese Americans don’t you assume the military also cares if your have relatives in Russia? Or even india? Or any country, especially ine that that isn’t five eyes?).
And yes you do have to have a solution. I am not in favor of people not being able to criticize societal injustices without a solution, but this isn’t really an injustice. No one has a right to state secrets or jobs that let you access them. Id you cannot show you have thought of the competing interests here and have some idea of what a real world solution to a hard problem might look like or take into account, then your criticism probably isn’t worth listening to (IMO).
You know this is how security clearances work today right? That when doing a risk assessment you look for ways in which the person in question may be pressured. How would you propose ensuring classified information stays safe? Do you have a solution?
Note that I am not taking sides in the purge-from-the-military people above. Just that your comment is out of touch with real world concerns.
