God made Israel a nation and he gave them a country. God commanded Israel to be fiercely nationalistic and to not allow dilution of their culture by external forces. If someone from the outside was to come in to Israel, then that person was required to conform to Israel's nationalistic cultural norms and practices.
A nation that has its national identity intact is blessed in that respect.
Conversely, a nation that has lost or is in the process of losing its national identity through dilution of its cultural identity by infiltration of foreign cultures and cultural influences is under the judgement of God. God uses people to execute this judgement, but he is the author of it.
Every nation on earth right now is having its national identity destroyed. Some are further along in the process than others, but all nations are having their culture diluted.
The artificial and engineered culture of the United States has for decades been used to destroy indigenous cultures around the world. Ironically, throughout the same time period conservative/Christian subcultures within the United States have been relentlessly undermined by this same pop culture, pornography, and the use of public schooling to disseminate and enforce humanistic ideals. At this point no part of the United States' system of cultures and their attendant elements can be said to be free of the virus of cultural destruction.
All cultures are being dissolved at this time in history in anticipation of their eventual coagulation into a single global governmental, economic and religious unity.
Nationalism is a gift from God, but if the people are ungodly they will not long retain it.
The ungodly Babylonish culture of the United States is truly the wine of the Great Whore and the entire world is gluttonous for it. This is not to say that the indigenous cultures of the world are any less ungodly.
All nations of the earth are antichrist and they are being unified under a single flag of the Great Whore.
When the process of global cultural infiltration/replacement completes this new global homogenized entity shall enjoy but a short reign before its termination, which most of us know very well is by fire from on high.
