They’re just bluffing, the aircraft plant is at best an empty dream when Saudi themselves don’t have required expertise to develop aircrafts.
This is different case. If they are bluffing then such they will be responsible in future!
All this is to make Bangladesh participate in Saudi dirty politics in the Middle East particularly ground offensive against Yemen and possibly Iran
Unfortunately you can't be totally neutral in this world. Khaleda zia said a bitter truth 15 February 1996 election and that is, "only a baby and a mad man can be neutral, so the concept of caretaker got is irrelevant".
So if we need to.join to any block, we must join to Saudi block ( without being hostile to Iran and Yemen), as the reality is Iran is Shia and majority of Bangladeshi is not only sunni, but a large numbers ( more or less 20% +) is ahle hadees, and a huge number of deobandis who are also Saudi sided.
Forget everything, just remember about our remittances, we need Saudi.
And also about ummah? How many Muslim countries are strongly siding kashmir? Pakistan is already upset because of the ummah and they know that Muslim countries have. Business with India and no one want to lose their market. First everyone want their convenience and then think about others.
That's the reason what Saudi is doing to Yemen, or what is their problem to Iran, that really isn't the case. Besides Iran is also silent about kashmir, so probably they don't want to offend India.
So that's the reason we also think about ourselves first. And then for rest of ummah. This word may be bitter, but that's reality!
So we must side Saudi Arabia,but we are not going to be hostile to Yemen or Iran, because this is out of the question.
