The APC was announced well before the earthquake hit Turkey. Ik and other PTI members already rejected participating in the APC. So, even if they APC is postponed for few days, the PTI already made up their mind about not attending it.
The issue with IK is that you can't trust him for anything he says. His flipflopping is still continue even after the PM.
This country doesn't belong to any party, any leader or any individual. This is a country or more than 23 million people. It doesn't matter if you are in power or not, if you are a real leader and sympathizer of the country, you should always consider the priorities of the country.
Pakistan is going through an economic meltdown. Never mind, who was responsible. It is time to sit together and come up with a common policy, nothing but for the sake of the country the economy policy should be the same.
But what IK wants? Just an election, at all costs. That is fine, however, let the current tenure of the parliament expire and then ask for the election at the end of the term. He has not rested a day without protest. In the situation Pakistani is in, let the current rulers (who stupid they may be) run the country in quietness and take it out of the crisis. But why would he do it? It feels like the rulers will be winning if they control the prices, bring back some sort of progress and work towards the solutions.
And that thought alone won't let him sit in piece.
