The anniversary of Iran is on the 22nd of Bahman which is 11 February. This marks the anniversary of the 1979 Iran revolution.
The Supreme leader Ayatollah Ali Khamenei said that Iran will deliver a punch on the 31st anniversary of the Islamic revolution. What is meant with that is yet to be known.
"The Iranian nation, with its unity and God's grace, will punch the arrogance (the West) on the 22nd of Bahman (February 11) in a way that will leave them stunned,"
There is a lot of speculation that they might showcase their new drones or maybe their new defense missile system that they announced today. Iran claims to have a missile defense system that is yet to be launched. Iran's Gen. Heshmatollah Kasiri said that the new missile system is more powerful than the Russian s-300 system which has a range of about 150km and a height range of about 27000 metres.
Whatever they will announce it cant be good since they also announced that Iran will start enriching nuclear fuel as early as Tuesday (tomorrow) for 10 nuclear plants they announced today.
Iran is about to raise their enrichment level from 3.5% to 20% which is also raising tensions with the US more.
So whatever Iran has up the sleeve for the 11th of February can only be speculated for now but a "punch" sounds a bit more drastic than just announcing a weapon or unmanned armed drones.
