這個地方太危險了吧，尤其對美國人民？

WARNING: Chad has experienced several bouts of political turmoil in the past few years and, although the security situation has slowly improved since 2010, the UK and U.S. governments advise against all but essential travel to Chad. Anywhere outside the capital, N'Djamena, is highly dangerous, especially in the north and east—where special travel/movement permits are necessary. Travel overland between Chad and Sudan, South Sudan, the CAR, Niger, & Libya is dangerous and highly discouraged. There is also a fairly high level of violent crime in much of the country.
