I can cite at least one reason to support your opinion that the call to BD by USA is a joke. It is that, it will lower the bad and undue influence of India in Afghanistan. When India is torturing its two Muslim countries, it is, at the same time is showing smiling face to the central asian Muslim countries, where India has no business.
If BD along with other Muslim countries, except Pakistan, participates, it will bring peace in the entire region. Once peace is re-established, the central asian region will be able to diversify its trade through Gowaddar Port in Pakistan. BD and even India can benefit from this. Now, you fully understand why it is such a big joke.
OK ,IF you send troops to Afghanistan
Not only is it the first time the BD has operated so far away from Home soil. It Would also be the First ever Overseas operation for BD(UN operations do not count).
There is a steep logistics and Operational Learning curve here. Not to mention the huge Financial cost of Fighting a war.
BD solders have also never fought or trained in terrain similar to Afghanistan.
BD soldiers mostly speak Bengali or some English if i understand right. So there is also a language barrier that has to crossed. So you will have troops who can't talk to the locals , you will be right back where the Americans were 8 years ago.
And if your thinking the Taliban will go easy on your "Muslim soldiers" , Keep in mind that the Taliban also kill the Afghan Police and attack the Afghan army. And they don;t exercise much restraint on that
So being Muslim and being a countrymen does not make a difference
to them. how much protection is it going to give you if your just Muslim. As far as they are concerned anyone who supports the war is an Enemy. Sure they may show more mercy but their tactics wont change any.
So Send BD troops, at great expense to BD all the way to Afghanistan.
What you will have is Soldiers who can't speak the local language.
An Army command struggling with Logistics and Operations.
Troops unfamiliar with the Terrain.
Fighting a war Which they have not been trained for .(Counter Insurgency)
A war being fought at great expense to BD.
Congratulation you will be exactly where the Americans were 8 years ago, expect less equipped , less funded and less experienced.
If that sounds like a good idea to you , feel free to call me an idiot.
Because i certainly cant see the benefit in any of it.
