Armed forces felicitate nation as it celebrates 26th Youm-e-Takbeer​

Tribute to all who contributed to the remarkable feat, honouring dedication and sacrifices, says ISPR

News Desk
May 28, 2024

On the occasion of the 26th anniversary of Youm-e-Takbeer, the Chairman Joint Chiefs of Staff Committee and Services Chiefs, on behalf of the Armed Forces of Pakistan, extended warm felicitations to the nation, the military’s media wing said in a statement on Tuesday.

This significant day commemorates the historic achievement of Pakistan's nuclear tests conducted in 1998, which successfully established credible minimum deterrence and restored the balance of power in the region, the Inter-Services Public Relations (ISPR) statement highlighted.

On May 28, 1998, Pakistan emerged as the first Muslim-majority country to acquire nuclear capabilities, marking a pivotal moment in its history. This achievement was a response to the regional security dynamics and ensured that Pakistan's defence capabilities were robust and credible.

Why is there a need to have a national holiday on this day?

Why can't they celebrate without announcing a national holiday?

Are the servants of the people or its chosen / selected ruling elite, going to pay the daily wage workers, who don't have a job / fixed pay or does this holiday benefits Pakistan economically?

Why is there a need to have a national holiday on this day?

Why can't they celebrate without announcing a national holiday?

Are the servants of the people or its chosen / selected ruling elite, going to pay the daily wage workers, who don't have a job / fixed pay or does this holiday benefits Pakistan economically?

Because its considered a massive achievement (not stating that I agree with the reason) for the country.

Considering that Pakistan is a security state with most of its history run by the establishment - it makes sense that they consider this their biggest achievement and with the seepage of military/aggressive mindset/bravado into the population the holiday was deemed to coincide with 6th September.

As far as why call it a holiday - that is on the decision makers although to be fair Pakistan has a lot less public holidays than many other countries in its neighborhood.

To be fair - most Pakistanis only work 4 1/2 days a week taking most of Friday off so it makes up for their lack of holidays.

Some have permanent years off until their child's grandfather hits the coffin from working the fields, and he'll then put his kids to work there. It's probably the only nation I see where things typically skip a generation,

 

[ghazi52]

I think no need for a holiday, a poor country like Pakistan, needs to work, not to sit at home doing nothing.
