Having an interest in what goes on around the world globally is really important.
But, since you ask, consider this. Trump, an extremely right wing president looks set to compete for a second term as president. The economy is improving, unemployment is improving....if his tenure is a success what will the rest of the world do? There will be many countroes that will want such strong extremism and will follow suit.
Politics should never be tied to the country you live in. It is how we learn what does and does not work.
