Should countries stay allies even if their leaders don’t get along?

I think countries should stay allies even when their leaders don't get along because it will help their economy grow quickly when the 2 countries are working together and it is more worth it than just 2 people getting along.It also helps both countries in numbers of amount of people working in the military.The economy will also grow as there will be a lot of people getting new jobs from the trades between the 2 countries.Mostly the countries will make a deal with eachother that would last longer than one leaders time controlling the country.They also help eachother in research and innovation because the engineers are able to work together on bigger projects that will help both countries in the long term not just one leaders run in the countries.When both countries are working together it helps them fix probelms like pollution viruses...It also bring tourism to the country that helps the country economic growth and their citizens in remote areas.
