If Iniquity Shall Abound Cursed Shall Be the Land for Their Sakes…But unto the Righteous It Shall Be Blessed Forever

Lehi, the Book of Mormon prophet, speaks of some of the special characteristics of the promised land as established by God in the Americas.

“[T]his land is consecrated unto him whom he shall bring. And if it so be that they shall serve him according to the commandments which he hath given, it shall be a land of liberty unto them; wherefore, they shall never be brought down into captivity; if so, it shall be because of iniquity; for if iniquity shall abound cursed shall be the land for their sakes, but unto the righteous it shall be blessed forever.” (2 Nephi 1:7)

Questions:

-Is there any land where God does not bless the obedient and withdraw blessings from the wicked?

-Has God established certain lands — such as the promised land of the Americas — where this dynamic of blessing and cursing is swifter and more pronounced? Why would He do so?

-Does iniquity abound in America (or areas within the Americas)? If so, are there signs of God withdrawing His favor from these peoples and places? Are their signs of liberty being lost?
