No. Christians should support peace and justice. We do not take any sides. When Israel does horrible things, we must not support it. When Iran does horrible things, we must not support it. When USA or NATO does horrible things, we must not support it. When Russia... etc.
We are on the Christ's side, not on the Jewish or American or EU or Chinese or Russian or Muslim side. Various nations do various things in various times, some good and some bad.
No today's nation, race or ethnicity is "the people of God" and none is "the people of Satan". Thats a terribly dangerous and fanatic talk, leading to pogroms, ethnic cleansing, religious wars and many historic injustices.
