Israel has already squeezed more then 100 billion USD so far from Germany alone!!!
Lets do a simple math... Israel receive for say around 5 billion USD for 7 million population. Bangladesh has 164 million... so with proportion to 5 billion it is 117 billion USD ... if it is around 10 billion USD for Israel including all direct and indirect aid which is equivalent of 234 billion USD if Bangladesh's population has been taken into account. So just imagine what 117 billion usd to 234 billion usd per as aid would do for Bangladesh!!!
Also let us take into account that BD only gained independence in 1972.
If BD had indeed become independent in 1947, then the possibilities are endless what it could have achieved. The jute "boom" in the 1950s and 1960s would have been used to power BD's industrialisation, rather than build infrastructure and the military of Pakistan.
