Foreign governments are certainly no better. However the government in the USA is certainly more capable and perhaps more motivated than most to act on the information it receives. There is also familiarity with the government carrying out the surveillance to be taken into account. For most European countries, particularly the one that have been members of the EU for some time there is quite good rule of law and so the consequences of being monitored are potentially less severe. Looking at governments with lots of resources to spare or ones without a good rule of law then surveillance is likely to make people more nervous - which is exactly the intent.
