In September, during an important by-election in Lahore, when the National Assembly's seat fell vacant following the disqualification of then-Prime Minister Nawaz Sharif, the newly launched MML backed an independent candidate who finished fourth in the race for Sharif's seat.

At the time, Pakistan's upper house of parliament strongly criticized the country's election commission for allowing JuD's political wing, MML, to participate in the Lahore by-election.

Some experts were concerned about the emergence of militant groups joining mainstream politics in Pakistan. They maintain that the political trend seen in Lahore's by-election, where parties linked to militant groups are able to mobilize and generate sufficient numbers of votes within a very short period of time, as alarming.

"There should be a debate on this sensitive issue through social, political and media channels. By allowing militant-based political parties to integrate into mainstream politics, it will only escalate radicalization in the society," Khadim Hussain, a Peshawar based political analyst, told VOA.

"There are people who believe with the merger of such militant groups into politics, we'll provide them an avenue to maintain a political presence without leaving their extreme ideologies," Hussain added.

Army's support

Earlier last week, Pakistan's army acknowledged they are mulling over plans to blend the militant-linked political groups into the mainstream political arena.

Some analysts side with MML, arguing the party should be allowed to participate in elections.

"I do not understand in what capacity the election commission has rejected MML's application to register as a party," said Ahmad Bilal Mehboob, the head of Pakistan Institute of Legislative Development and Transparency (PILDAT).

"Did they (MML) break any law? If not, how can you bar MML from entering the mainstream politics when they're doing it through legitimate ways," Mehboob emphasized.

Zubair Iqbal, a Washington-based South Asia expert, also raised concerns over the validity of the decision.

"This is how democracy works. … There are some extreme groups, some moderate groups and no one should be stopped because of their extreme ideologies," Iqbal told VOA. "The extremist groups can be barred from entering into the politics only through people and democracy."

"Unless these parties and individuals are allowed to participate in the political system they might never change their extreme ideologies and might continue operating underground which will prove to be more dangerous," Iqbal added.

International pressure

In the past few years, Pakistan has faced escalating pressure from the international community for not being able to crackdown on militant groups enjoying safe havens in Pakistan and launching attacks in neighboring countries.

In his recent speech on the region, U.S President Trump put Pakistan on notice to take actions against safe havens in Pakistan. Pakistani officials deny the existence of safe havens on its soil.

Pakistan is also accused of being selective in its pursuit of terror groups. It allegedly goes after only those groups that pose a threat to the country's national security, ignoring others that threat India and Afghanistan.

Pakistan rejects the allegations and reiterates its stance of having no sympathy for any terror group operating in the country.(VOA)
