And (as a Brit) I'd say I'd think of Argentina, Brazil, Australia, Korea and probably plenty of others before I thought of USA.

The USA has regionally specific bbq varieties that will blow your mind.  Its all hardwood smoked, slow and low, sometimes over 12-14 hours and every region uses different woods, meats, and types of sauce.  Here in the coastal southeast, pecan smoked pork and chicken is served with a mustard based sauce.  In texas, youre more likely to get beef brisket smoked in hickory with a tomato and molasses type of sauce.    Some good ribs, smoked properly, are a religious experience. Between the seasoning rub, the smoke flavor, the burnt ends, and the sauces (the recipes are guarded like fort knox) the USA takes bbq VERY VERY VERY seriously

It might not be as internationally famous, because its hard to recreate without access to specific kinds of wood and cuts of meat, but NOBODY does BBQ like americans do.  Korean "bbq" isnt even really bbq.  There is a difference between grilling and barbecueing, which requires smoke to do properly.
