When Did We Declare War On Somalia?

Anybody else bothered by this?
From the New York Daily News: International military forces carried out a pre-dawn strike Saturday against foreign fighters in the same southern Somalia village where U.S. Navy SEALs four years ago killed a most-wanted al-Qaida operative, officials said.
The strike was carried out in the town of Barawe in the hours before morning prayers against what one official said were "high-profile" targets. The strike comes exactly two weeks after al-Shabab militants attacked Nairobi's Westgate Mall, a four-day terrorist assault that killed at least 67 people in neighboring Kenya.
The leader of al-Shabab, Mukhtar Abu Zubeyr, also known as Ahmed Godane, claimed responsibility for the attack and said it was in retaliation for Kenya's military deployment inside Somalia. In Kenya, a military spokesman released the names of four men implicated in the mall attack.
A resident of Barawe - a seaside town 240 kilometers (150 miles) south of Mogadishu - said by telephone that heavy gunfire woke up residents before dawn prayers. An al-Shabab fighter who gave his name as Abu Mohamed said "foreign" soldiers attacked a house, prompting militants to rush to the scene to capture a soldier. Mohamed said that effort was not successful....
Foreign militaries - often the U.S. but not always - have carried out several strikes inside Somalia in recent years against al-Shabab or al-Qaida leaders, as well as criminal kidnappers. A Western intelligence official said it appeared likely that either U.S. or French forces carried out the attack. The official insisted on anonymity to discuss intelligence matters.

So, now, we have the Navy SEALs acting as police officers. going into countries we have not declared war on and arresting thugs who have committed crimes, at least according to the Obama administration.
It used to be we would send in the FBI and other police agencies to do this dirty work, not the military.
And, oh by the way, the raid failed to bring in the main guy they were looking for.
