Why are the diplomats of the world's most powerful countries flying and traveling all over the world all the time?

Why are their military engaged in active military diplomacy, planning, and frequent exercises all over the world in the same way?

Are they doing it for national security, for public relations, for peace, for fun, or for prestige?

Do they have to do all this in such an elaborate and expensive way?

If nations of the world could stop engaging in aggressive foreign policy and massive buildup of military force, the risks to peace, stability and global climate will be reduced significantly.

If more video conferencing is used for all kinds of consultations and transactions, the carbon footprint of humankind and the risk of climate change will be significantly reduced.

This is the only way to a peaceful and prosperous future for all humankind.
