SANAA/DUBAI (Reuters) - An intense two days of air strikes on al Qaeda in Yemen may have killed or wounded some of its commanders, but drones alone are unlikely to eradicate the threat the group poses to Yemenis and the West.
A weak central government, a rivalry-ridden and poorly equipped security force, endemic poverty and corruption have made Yemen the ideal haven of al Qaeda in the Arabian Peninsula (AQAP), whom U.S. President Barack Obama has described as the group "most active in plotting against our homeland".
Desperate to prevent AQAP from planning more attacks like its attempt to blow up a U.S. airliner in December 2009, Washington has used drones to strike and kill group members and leaders.
But analysts say drone strikes do only limited harm to AQAP.
They say the group will remain a serious menace unless the government can address challenges like poverty and inadequate security forces, and curb the occasional civilian casualties inflicted by drone attacks that inflame anti-U.S. sentiment.
"The U.S. can't simply kill its way out of the terrorism threat," said Letta Taylor, Human Rights Watch's senior researcher on terrorism and counter-terrorism.
"The U.S. and other concerned nations should address all the drivers of terrorism including poverty, illiteracy, political marginalization and lack of opportunity for young people."
DRONES WON'T END WAR
The drones' main success has been to severely limit AQAP's movements and ability to hold territory as it did back in 2011.
"When they move from A to B, they have to think 100 times. They've lost their freedom," said Mustafa Alani, a security analyst with close ties to the Saudi Interior Ministry.
"It (drones) is very effective, but this is not going to deal with the problem. These people are replaceable. You can kill 10 of them and there's 10 more in the pipeline. (So) it's a success that won't end the war against AQAP," he told Reuters.
On Saturday and Sunday, several air strikes - presumed to be
carried out chiefly by U.S. drones - were launched on central and southern provinces of Yemen, killing as many as 40 al Qaeda militants, according to local and tribal sources.
Yemen's government has not disclosed the complete number of militants killed. A senior security source said investigations were being carried out into the identities of those killed, but confirmed that "leaders in the organization" had died.
Rumors have been swirling that those killed include AQAP leader Nasir al-Wuhayshi and Saudi bombmaker Ibrahim al-Asiri, especially after several eyewitness reports emerged that at least one helicopter had landed after a late Sunday night strike in the restive southern Shabwa province.
Tribal sources told Reuters on Sunday that five suspected militants were killed in that attack.
"Minutes after the car (with militants) was hit, we saw helicopters hovering overhead and military cars spreading. Soldiers were seen disembarking from one of the helicopters," said Obeid Awad.
"After they left, we found the struck car but we could not find any body parts," he told Reuters.
Local and tribal sources over the weekend said unmanned drones had been circling for days prior to the attacks. Yemen is among a handful of countries where Washington acknowledges using drones, though it does not comment publicly on the practice.
Faris al-Saqqaf, an advisor to the Yemeni president, told Reuters that Yemeni fighter MiG-29s joined in the operation in Shabwa.
CIVILIAN CASUALTIES, RECRUITMENT OPPORTUNITIES
"Drone strikes are never the solution. It is a tactical band-aid but it can be quite an important one if you don't want to see planes dropping from the sky in the West," said Magnus Ranstorp, a terrorism expert at the Swedish National Defence College.
Yemeni President Abd Rabbu Mansour Hadi praised the anti-terrorism unit in Yemen's special forces for their strike in Shabwa, which he said targeted "dangerous leading elements of al Qaeda" and described the operation as one "that represents a strong message to the elements of evil and terrorism".
Ranstorp said Hadi's public announcement could "change the assessment" that more senior members were targeted.
But the use of drone strikes has inevitably meant that civilian casualties are sometimes inflicted.
The government acknowledged that three civilians were killed in an air strike on Saturday that also killed 10 militants in the central al-Bayda province -- which also witnessed a controversial strike in December in which security officials said 15 people on their way to a wedding were mistakenly killed.
Yemeni political scientist Abdulghani al-Iryani points to the sharp increase in the number of al Qaeda elements from when the drone campaign started in 2003, when they were a few hundred to the several thousand they are believed to be today.
"There are many reasons for the increase of membership of al Qaeda, but we cannot rule out that the use of drones and the popular backlash it produced has increased the recruitment opportunities of al Qaeda," Iryani told Reuters.
"The fact that both the Yemeni and the U.S. governments have relied too heavily on the use of drones as an expedient way to postpone the resolution of the problem rather than having a proper, comprehensive approach to the problem, has contributed to the expansion of al Qaeda in Yemen," he said.
RECIPE FOR DISASTER
Yemen said the attacks were carried out after intelligence that the militants were planning attacks on "vital civil and military and installations".
The appearance of an online video a month ago in which Wuhayshi appears brazenly with hundreds of other fights, vowing to attack the United States while celebrating the escape of al Qaeda prisoners from Sanaa's central prison, may have helped provide some clues.
Saqqaf, the president's adviser, described the video as 'provocative" and said it showed the location in which al Qaeda elements were present.
But the army's weaknesses in providing security in swathes of the country helps gives AQAP more freedom, making drones "an easy option to attack specific targets in a timely manner", said Charles Lister, a visiting fellow at the Brookings Doha Centre.
"But the lack of on-the-ground military presence means a lack of localized intelligence, which by extension means strikes have inevitably struck civilian targets on occasion. In a deeply tribal and conservative society, such incidents are a recipe for disaster," he said.
"While a drone strike might represent one step forward, more often than not, it also means two steps back."
