US Secretary of State Rubio has always supported a tough policy; he does not like negotiating with countries like Iran, Palestine, and Venezuela, preferring sanctions and pressure.
Many people think that if Trump really wants to make the world more peaceful, he should replace Rubio, negotiate more with other countries, and use less force.
Only then can the US have a chance to build better relations with countries in Latin America, the Middle East, and other regions, reducing wars and increasing peace.
