Maybe you are not a smart person... so i´ll help you.
Yes, brazil is dangerous, i´ve never said the opposite, and in any moment i said its because of the number of the population. Japan has 120 million of people and is safe.
But a smal country, with 4 million of people, it must be safe ofc.
USA is the biggest economy of the planet, but its not safe as Belgium, and that´s because of the number of the population.
Do u understand now ?
