These curses shall be a sign to us as the descendants to identify who we are and where we come from. The reason for the curses is a failure to keep the law. The curses can be seen as consequences. In this section of the Bible, blessings and curses were given as consequences for following YHWH's law or disobeying it.
Deuteronomy 28:45 “Moreover all these curses shall come upon you and pursue and overtake you, until you are destroyed, because you did not obey the voice of the Lord your God, to keep His commandments and His statutes which He commanded you. And they shall be upon you for a sign and a wonder, and on your descendants forever.
Destroy refers to the state of Israelites becoming slaves and forgetting who they are. By the time the shackles were taken off, the enemy was sure that the Israelites were then mentally enslaved. The eagle is significant and Edom uses this symbol throughout the ages of oppressing us through Rome, USA, Edom.
Deuteronomy 28:47 “Because you did not serve the Lord your God with joy and gladness of heart, for the abundance of everything, therefore you shall serve your enemies, whom the Lord will send against you, in hunger, in thirst, in nakedness, and in need of everything; and He will put a yoke of iron on your neck until He has destroyed you. The Lord will bring a nation against you from afar, from the end of the earth, as swift as the eagle flies, a nation whose language you will not understand, a nation of fierce countenance, which does not respect the elderly nor show favor to the young. And they shall eat the increase of your livestock and the produce of your land, until you are destroyed; they shall not leave you grain or new wine or oil, or the increase of your cattle or the offspring of your flocks, until they have destroyed you.
The true Israelites will be scattered among the nations and forced to worship world religions their idols of wood and stone and will be at the bottom everywhere they are scattered and their life will always be at risk as a nation.
Deuteronomy 28:64 “Then the Lord will scatter you among all people, from one end of the earth to the other, and there you shall serve other gods, which neither you nor your fathers have known—wood and stone. And among those nations you shall find no rest, nor shall the sole of your foot have a resting place; but there the Lord will give you a trembling heart, failing eyes, and anguish of soul. Your life shall hang in doubt before you; you shall fear day and night, and have no assurance of life.
The Israelites will go into slavery again just like they did in Egypt, but this time in ships and will never again see their homeland again.
Deuteronomy 28:68 “And the Lord will take you back to Egypt in ships, by the way of which I said to you, You shall never see it again.’ And there you shall be offered for sale to your enemies as male and female slaves, but no one will buy you."
Because of perpetual sin, the descendants of Israel won't know who they are, sin is the transgression of the law.
Isaiah 1:3-4 The ox knows its owner And the donkey its master’s crib; But Israel does not know, My people do not consider.” Alas, sinful nation, A people laden with iniquity, A brood of evildoers, Children who are corrupters! They have forsaken the Lord, They have provoked to anger The Holy One of Israel, They have turned away backward.
Hosea 4:6 My people are destroyed for lack of knowledge: because thou hast rejected knowledge, I will also reject thee, that thou shalt be no priest to me: seeing thou hast forgotten the law of thy God, I will also forget thy children.

What is so special about the Israelites?
2 Esdras 5:23-27 "And said, O Lord that bearest rule, of every wood of the earth, and of all the trees thereof, thou hast chosen thee one only vine: And of all lands of the whole world thou hast chosen thee one pit: and of all the flowers thereof one lily: And of all the depths of the sea thou hast filled thee one river: and of all built cities thou hast hallowed Sion unto thyself: And of all the fowls that are created thou hast named thee one dove: and of all the cattle that are made thou hast provided thee one sheep: And among all the multitudes of people thou hast gotten thee ONE PEOPLE: and unto this people, whom thou lovedst, thou gavest a law that is approved of all."
Deuteronomy 32:9 “For the LORD'S portion is his people; Jacob is the lot of his inheritance.”
Psalm 147:19-20 "He sheweth his word unto Jacob, his statutes and his judgments unto Israel.  He hath not dealt so with any nation: and as for his judgments, they have not known them. Praise ye the Lord.
The Israelites are so-called schemetic black people.
Song of Solomon 1:5 "I am black but lovely, O daughters of Jerusalem, Like the tents of Kedar, Like the curtains of Solomon.
Lamentations 4:8 Their appearance is blacker than soot, They are not recognized in the streets; Their skin is shriveled on their bones; it is withered, it has become like wood.
Daniel 7:9 "I kept looking Until thrones were set up, And the Ancient of Days took His seat; His vesture was like white snow And the hair of His head like pure wool His throne was ablaze with flames, Its wheels were a burning fire.
Revelation 1:14-15 His head and His hair were white like white wool, like snow; and His eyes were like a flame of fire. His feet were like burnished bronze, when it has been made to glow in a furnace, and His voice was like the sound of many waters.
All the nations will conspire to hide and cut off the Israelites from being a nation. Until this day, the entire world seems to have something against the black people of the world. It could even be some nations that are just as 'dark' in complexion, nevertheless, somehow carry this spiritual energy that is against the children of Israel.
Psalm 83:4 They have said, “Come, let us cut them off from being a nation, That the name of Israel may be remembered no more.” For they have consulted together with one consent; They form a confederacy against You: The tents of Edom and the Ishmaelites; Moab and the Hagrites; Gebal, Ammon, and Amalek; Philistia with the inhabitants of Tyre; Assyria also has joined with them;
1 Maccabees 3:48 And laid open the book of the law, wherein the heathen had sought to paint the likeness of their ima
There will be a time where another nation of people will claim they are Jews but are not and will not fit any of the prophecies perfectly like the true Israelites.
Revelation 2:9 I know thy works, and tribulation, and poverty, (but thou art rich) and I know the blasphemy of them which say they are Jews, and are not, but are the synagogue of Satan.
Luke 21:24 And they shall fall by the edge of the sword, and shall be led away captive into all nations: and Jerusalem shall be trodden down of the Gentiles, until the times of the Gentiles be fulfilled.
The descendants of the Israelites will be subject to false prophets and religions and most will believe the lies.
Matthew 7:14 Because strait is the gate, and narrow is the way which leadeth unto life, and few there be that find it.
Matthew 5:19 Whosoever therefore shall break one of these least commandments, and shall teach men so, he shall be called the least in the kingdom of heaven: but whosoever shall do and teach them, the same shall be called great in the kingdom of heaven.
