DHS didn't exist but most of the components existed (secret service, coast guard, customs and immigration, FEMA, etc). They just got moved from the departments of treasury, transportation, etc into DHS. It's not like all of that came out of nowhere. The big part of DHS that was new was TSA, for obvious reasons. There's also a ton of growth around cybersecurity, which is a good thing.
