Serious question: If they weren't Catholics, say for example they were Eastern "Orthodox", would Catholics be duty/morally bound to care?
Yes. For e.g. when Orthodox Christians were being persecuted by Bolshevik Communists, among whom were many Jєωιѕн extremists, as we know, the Papacy cared for them and tried to stop it, while of course continually them to give up the schism and return to Roman Catholic unity. So yes, if other Christians are persecuted, we try to stop it.
The US has been killing people for the Jєωs since it became powerful enough. It makes no sense at all to expect it to change now.
That depends on who gets into office. If JFK had remained President, he would have pushed back more against the Zionists. He was of course αssαssιnαtҽd precisely for doing that.
Raegan did so too. "In 1983, Reagan reaffirmed that he would not send F-16 jets to Israel until Israel withdrew its forces from Lebanon." https://www.axios.com/2024/05/13/us-presidents-red-lines-israel
I shared earlier that Trump on X/TS praised a Polish Catholic priest who died a heroic death resisting Communism. He also converted an atheist communist kgb official on the spot by his bravery. When Trump was in Poland, he praised their stand against Communism and sounded Raeganite. Hopefully, he will follow Raegan's policy with Israel too. But it is difficult, as the case of JFK clearly shows us, because of the power of the zionist lobby/aipac etc as Thomas Massie knows and finds out. Very brave man, Thomas Massie, for courageously and heroically resisting them.
