Generally, security rules are made and enforced by USA authorities. Any airport which doesn't fly to the USA only needs to follow local rules of the country they are in, which while typically are as strict as the USA rules, are typically not enforced.
Some airports for example only xray one in 10 bags at peak times, or none at all if the machines broken.
