Nations form alliances in order to achieve goals that otherwise wouldn't be possible. For example, NATO, or the North Atlantic Treaty Organization, a coalition of countries in North America and Europe, agree to defend one another in case of attack from an outside party. This is clearly beneficial, because this intergovernmental support both makes an outside attack less probable, and if it occurs, easier to handle. Another example is NAFTA, or the North American Free Trade Agreement. Shared among Canada, the US, and Mexico, this alliance eradicated trade barriers within these countries. Another beneficial alliance, this agreement increases international trade due to lower costs and thus improves the international economy.

Some people can achieve any task faster than others, but it doesn’t mean that the one “slow” is less intelligent, he just takes more time to finish the same task.  
Slow processing is not a learning problem and it is not related with intelligence, but it can impact in all stages of learning. In this way, speed can contribute to learning difficulties such as ADHD, dyslexia, dyscalculia or auditory processing disorder.
It can also be impaired when coexists with autism spectrum disorders, and in other pathologies such as dementias or diseases such as schizophrenia.
