One of the workings by the coming false Messiah, per prophecy in the Book of Daniel, is his use of 'peace' to destroy many (Daniel 8).
In 1 Thessalonians 5, Apostle Paul showed that when 'they' (meaning the deceived) say, "Peace and safety", then "sudden destruction" shall come upon them. Paul was pointing to God's consuming fire on the day of the Lord that is to happen on the very last day of this world, with Christ's return (see 2 Peter 3:10).
In Matthew 24 about the end of this world, Jesus gave the Sign that we would hear of wars and rumors of war, but be not troubled because those things must happen, BUT THE END IS NOT YET. The opposite of a time of war and rumors of war is a time of world peace. Thus the coming tribulation is to be a time of world peace, but a fake peace.
In Revelation 13, we are asked who can make war with the beast? The idea is when he comes to power with his beast kingdom, over all nations and peoples, he will control all militaries and armies. No nation will be able to make war. This is the main proposed goal of the United Nations, to end all wars and bring world peace, literally.
But the actual real... goal that Satan's servants in control today do not let be known, is his plan to takeover the whole earth and rule over all nations as "king of the world", and to be worshiped in place of God. Those who refuse to bow to him or his image are to be killed (Revelation 13). That is what Satan has always wanted, to be worshiped as GOD. That is what he rebelled about in the old world when he fell, and it will be what the coming tribulation at the end of this world will be about.
