Will the kingdom in Daniel 2 be on earth and cover the whole world rather than only Palestine?
Yes. Daniel 2's kingdom will be on the earth, and it will cover the whole earth, not merely Palestine. It will be a glorious, productive physical kingdom with no curse, sin, want, poverty, or famine, and Christ will rule over the planet.
Les explains that the Kingdom Daniel prophesies in chapter 2 is not limited to Palestine. It will indeed be on the earth and cover the whole earth. He describes it as a glorious earth where everything is productive, with spears and swords beaten into plowshares that prepare the earth for production. There will be no want, poverty, or famine. It is a physical kingdom, yet also a glorious spiritual kingdom because there is no curse and no sin. It is political because Christ will rule over the planet. Les also notes that Scripture interprets itself, and Daniel 2 continues with the king being addressed as king of kings.
