Three Examples of Elohim Judging a Nation That Broke a Covenant with Him

After Kind David passed away, his son Solomon became king of Israel. King Solomon built the first temple in Jerusalem and was given great wisdom and riches by Yahu Elohim. King Solomon received tribute from many nations and made treaties with them and married the daughters of many kings. Unfortunately, just as King David had committed adultery with Bathsheba and schemed to have her husband killed, King Solomon also sinned in the area of woman. It is forbidden to marry a non-Israelite woman because she may not worship Yahu and she will lead her husband's heart astray. All these foreign wives that King Solomon had led his heart away from serving Yahu Elohim with his whole heart. Because of this after King Solomon passed away, Yahu spit the kingdom of Israel into the southern kingdom, which King Solomon's son ruled over which is called Judah consisting of the tribes of Judah, Benjamin and some Levites and the northern kingdom consisting of the other 10 tribes which is called Israel.

Jereboam, leader of the ten tribes of northern Israel was afraid of having the people go to celebrate Yahu's appointed festivals in Jersualem because he was afraid they would join the kingdom of Judah and defect. So Jereboam made golden bulls as gods I believe and appointed his own priests and not Yahu's appointed Levite priests. Jereboam sinned greatly in this and in 722 BC I believe, Yahu Elohim sent the Assyrian army to invade Israel and conquer the Israelites. The 10 tribes were scattered throughout and many today who are of these 10 tribes no longer realize they are Israelites who are commanded to keep the covenant with Yahu.

Later, Judah also fell into idolatry and Yahu sent the prophet Jeremiah to warn them to repent of their sin but they refused. Jeremiah told them to surrender to King Nebuchadnezzar of Babylon but they refused and so the Babylonians attacked and captured Judah. Judah was exiled for 70 years in Babylon so that the land could enjoy it's land Sabbaths which the Jews had not observed. After this some Jews were allowed to return to the the land and rebuild the temple.

In 30 AD, when Yashua the anointed one came, the church of his time which was led by the Pharisees and Saducees, rejected Yahshua the Messiah and plotted to have him killed. Even though Yahshua did miracles and even resurrected Lazarus, the priests of his day had him killed perhaps because he was a threat to their leadership, perhaps because they were jealous of him. To this day, most Jews repeat the mistake of their ancestors in rejecting Yashua rather than repenting of and confessing the sins of their ancestors. But because they rejected their Messiah, in 70 AD the Romans came and destroyed Jerusalem and scattered the Jews throughout the world in what is called the Diaspora.

Now America has also broken it's covenant with Yahu Elohim and because of this will be judged with 7 years of famine although it may be less in some areas, suffer through a depression worse than the Great Depression with a stock market crash and the dollar eventually becoming worthless, plagues like bird flu, a white blister plague and an ebola type plague, will have gangs acting like wild animals going around killing, raping and looting, will have multiple cities being attacked with bombs possibly dirty nukes, have electricity problems possibly because of solar CMEs or cyber attacks, will experience a huge Utah earthquake, the big California earthquake where a large chunk of California falls into the ocean causing world wide tsunami, a New Madrid earthquake that splits the USA along the Mississippi River thus Yahu divides our land because we divided Israel, Russian subs nuking California, New York State, Florida and Las Vegas with the Russians invading from the east coast and Chinese and Japanese invading from the west coast with Cuba, Nicaragua, Mexico and two other nations helping them and then 7 years under captivity until Yahu relents and Americans led by a godly leader run out the Russians and Chinese but America will be destroyed and most of its population dead for not keeping Torah, not keeping it's covenant with Yahu, for turning it's back on Yahu.

As King Solomon said, there is nothing new under the sun.
This has happened at least three times before and it's going to happen again with America. Prepare yourself by accepting Yahshua as Messiah, repenting of your sins, confessing the sins of your fathers, keeping Torah and the everlasting covenant and listening and heeding the prophets and apostles of Yahu Elohim.

As much as i like American people, I dun think anyone godly, or "godly leader" can emerge from there. The brainwashed Americans dunno where Iraq is but started a war. The dumbing down education system ensures it can never happen.
And China and Russia would not invade. America will fall by itself, civil war and economic catastrophe. No one would waste a bullet. They just need to wait. Your notion of war makes you so American. Almost all the wars in last 2centuries are instigated or started by America.
You can be surprised by how much better the world will be without American leaders.
