@Deino - Well currently were not spending 2% of our GDP on defence (its between 1.2% and 1.6%). Regardless, our GDP is growing @ roughly 7% and defence purchases are paid over multiple years so a deal for J10/Su35 can be afforded easily (unless there is a severe economic downturn).
For example 16 J10b's @ $60m each should cost roughly $1.2bn-$1.6bn. Paid over 15-20 years, would mean paying the supplier just over $107m per year. Su's would like wise be similar in price....at current GDP growth rates easily within budget.
On a sidenote by the end of the contract term 15-20 years, Bangladesh would be $1trn economy....
