US sergeant says he is under investigation for sharing anti-Israel social media posts

So after 20 years of service in the military, yesterday I got pulled into an officer's office and counseled for posts that I have on my social media. During the counseling, they told me I'm under investigation as a threat to national security. When I asked for proof like what the posts were yesterday they refused to give it to me. They made me come back today to further go over stuff. They gave me the proof and the proof they gave me are anti-Israel

posts. Now I joined, when I joined the military, I took an allegiance to support the United States of America. I did not ever take an allegiance to support Israel. But yet, I am deemed a national threat to national security because I do not support Israel and their genocide against the Palestinian people. Yes, you heard that right. I am deemed a threat to national security because I don't support Israel's genocide against the Palestinian people. Since when does not supporting a foreign nation

national security because I don't support Israel's genocide against the Palestinian people. Since when does not supporting a foreign nation get a US soldier investigated for being a threat to national security?
