"The LORD will mediate between nations and will settle international disputes. They will hammer their swords into plowshares and their spears into pruning hooks. Nation will no longer fight against nation, nor train for war anymore" (Is. 2.4). There won't be international disputes in eternity future, only in the millennial kingdom. And in the millennial kingdom there will no longer being nations fighting. That's not happening now.

"No more shall there be in it an infant that lives but a few days, or an old man who does not fill out his days, for the child shall die a hundred years old, and the sinner a hundred years old shall be accursed" (Is. 65.20). Children die quickly through malnutrition or from being born into sin. Children will not die in eternity future. So this time spoken of if not now or eternity future, must be the future millennial kingdom. 10,000 children die of starvation every day or from other abuse.

"For the earth shall be filled with the knowledge of the glory of the LORD, as the waters cover the sea" (Hab. 2.14). This is certainly not the condition today. Most people I speak to reject the Lord.
