Cursed Is This Land unto Every Nation, Kindred, Tongue, and People Which Do Wickedly

Alma teaches that the Americas (or at least the portion of the Americas that the Nephites once inhabited) is cursed by God towards any nation or societal group who chooses wickedness. Wholesale destruction will ensue when that wickedness reaches a maturation point that is intolerable to God.

“Thus saith the Lord God—Cursed shall be the land, yea, this land, unto every nation, kindred, tongue, and people, unto destruction, which do wickedly, when they are fully ripe; and as I have said so shall it be; for this is the cursing and the blessing of God upon the land, for the Lord cannot look upon sin with the least degree of allowance.” (Alma 45:16)

Questions:

-Are there signs that North America (or certain nations/regions within it) is maturing toward destruction because of wickedness? Does the same apply to South America? Or certain places there?

-How many are left who are willing to repent in the name of Jesus Christ? Or, who understand how important it is to do so?
