The worst country for Moslem terrorism in 2016 was not Syria but Iraq: 798 incidents, 9,663 deaths.
Syria came second: 309 incidents, 3,325 deaths.
Nigeria came third for deaths: 1,744.
Afghanistan came fourth: 1,424.
Somalia came fifth: 761.
Libya came sixth: 732.
Pakistan came seventh: 730.
Yemen was eighth: 684.
Egypt was ninth: 344.
DRC was tenth: 202.
The US was 23rd, with 7 incidents yielding 49 deaths.
The UK had 5 incidents and 4 deaths. (There are a similar number of Moslems in the UK as in the US, so I suppose you might say Britain integrates its Moslems more effectively than the US does).
This doesn't count the foiled terrorism incidents.
