I highly recommend a book called AS AMERICA HAS DONE TO ISRAEL. It lays out the incredible correlation of good/bad that happens to the USA at moments when we are dealing favorably/unfavorably with Israel. It makes perfectly clear that God's promise to bless those who bless Israel and curse those who curse Israel, is very much intact and in force.
If only those pseudo intellectual elitists in Washington would get the message. But, there are many of us praying for Israel and I pray God honors our prayers.
