Us sunnis also know well the event of Karbala. In the end, we need to realize the following.
1. The entire mess was started by US interferring in Middle East.
2. Iran has been fighting American forces and Israeli forces in the Middle East.
3. Iranian general died in blatant US strikes while bringing a message for Iraqi Prime Minister about the peace negotiations between Saudi Arabia and Iran. Pakistan has openly said it has been facilitating this in the past.
4. Iran while it has had rough share of damage on Pakistan, lets not forget they have also suffered from rogue Baloch militias. Lastly, they have been on better terms with us lately.
5. They are muslims, and fighting for good, and it would be stupid of us to think that Iran won't attack if their General was killed.
If Pakistan is forced to choose a side, then so be it, we must by all means not side with US, rather against it.
Our revenge for all those drone attacks, attacks on our sovereignty, civilians deaths, attacks on our soldiers, CIA operations, the abandonment after Afghan War, is long, long overdue! Pakistan wants the US to exit Afghanistan as well as the Middle East theatre just as much. Whoever brings sectarianism in a time when another Islamic powerhouse is on the American hitlist, is playing into the regional interests of Israel.
Here's what Prime Minister of Malaysia, Mahathir Muhammad said.
