What they really think: America seen through the world's travel warnings

(CNN)If your friends and allies won't tell you what they really think, check their travel advisories.

Uruguay and Venezuela aren't the only countries to have issued travel warnings about the risk of gun violence in America -- though their language citing "hate crimes" and the "supremacist elite" in Washington was head-turning in the wake of deadly shootings in El Paso, Texas and Dayton, Ohio.
Close US allies have long warned their citizens about the risks of exploring the United States. And while most online advisories rank the US as safe to visit, many also make mention of domestic mass shootings, typically categorized as terrorism -- and also warn about the astronomical cost of American health care for visitors whom misfortune befalls.
    Sometimes politically pointed, but more often simply pragmatic, each country's travel advisories are usually published only in the local language. And because they're designed to keep their own citizens out of trouble, the frankness with which such documents review US security, health, local law and customs can offer a fascinating portrait of America -- which Americans themselves may struggle to recognize.

    Warnings about terrorism and mass shootings

    Canada, which is right up there alongside the US in terms of gun ownership, advises its citizens to "take normal security precautions" in the US, and notes that "incidents of mass shooting occur, but account for a small percentage of homicide deaths in the country." With 34 guns for every 100 people, Canada ranks fifth in the world for gun ownership according to the Small Arms Survey. The US is first, with 120 firearms per 100 people.
    "The likelihood of a tourist being a victim of such a (mass shooting) incident is low," adds Canada. Although US gun homicide rates far outpace those of fellow wealthy countries, the likelihood of any individual being a victim of such an incident remains statistically low, though no less horrifying.
    New Zealand, itself the recent victim of a large-scale mass shooting, offers the most detailed travel advisory -- if also somewhat out of date, having been last reviewed in November 2018. The country's website calls for "increased caution in the United States due to threat of terrorism" and reminds New Zealanders that the US has suffered multiple "politically motivated" attacks.
    "Active shooter incidents occur from time to time in the United States," the advisory adds in a "Crime" section. It does not gloss over America's bloody recent history of mass shootings, listing a May 2018 school shooting in Santa Fe, Texas; a November 2017 church shooting in Sutherland Springs, Texas; and October 2017's concert shooting in Las Vegas, Nevada -- the deadliest in modern US history.

    Ireland's short travel advisory notes simply that while terror and extremist violence has increased worldwide, the US in particular "has also witnessed a number of mass shootings in recent years." Meanwhile, Italy's travel profile for the United States says that terror attacks remain a threat in large cities, and warns that "serious firearm incidents" sometimes occur in smaller communities as well.
    Both New Zealand and Italy defer to US expertise in mass shootings, advising travelers to consult the US Department of Homeland Security website for tips on what to do in such an attack.
    In contrast, the United Kingdom's travel advisory politely eschews mention of potential mass shootings, though it describes terrorists as "very likely" to attempt attacks in the US, inspired b
