AL and India is probably scared of IKB take over. They will try to launch a counter coup and kill IKB, if a coup happens and if it is true that IKB is not pro-India but pro-Bangladesh. So there is great danger in a coup for loosing some valuable pro-Bangladesh people to the pro-India killers on the loose in Bangladesh.
So as @
aazidane mentioned earlier, IKB date of retirement is in June and so if a coup does not happen by that time, AL will try to retire IKB and promote the pro-India guy (I forget his name) to the top Army post, so Army can help AL to come to power through a rigged election.
If we are really a "democracy", Bangladeshi's deserve and should demand for a free and fair election under army supported neutral CTG rule. AL's coming to power through a rigged election with support of a pro-India army chief will show proof positive that Bangladesh is not a real "democracy", but a dictatorship, where AL stays in power with India's help and support.
I personally support AL's coming to power in a rigged election with India's help, as that would make our countrymen understand the real nature of Awami League, an anti-democratic dictatorial fascist Indian agent that wants to make our country a vassal state of India.
Only after our great majority, the 90% understand the true nature of Awami League, can there be a mass revolt against Awami League that will be supported by Army Jawans, even though there are a few pro-India officers sitting at the top, placed there by Awami League.
As for the trials, these are not important now, there will not be fair trial anyways, unless we have a true free and fair election and a truly democratic govt. comes to power. Only then there can be questions about trial of past crimes, and there has been many starting with AL killing of 40,000 politicals opponents by RAW creation Mujib Bahini (that sit out most of the liberation war in 1971) in 1972-1975 (including many Mukti-Bahini freedom fighter soldiers), down to this Pilkhana massacre of 57 Army officers.
The next 9 months will be about struggle for power and what kind of election we will have at the end of AL term at the end of this year. So lets not worry about these trials, they are not for an interim Army govt. or a CTG govt. to tackle, they have to wait for a bona fide democratically elected govt. who has the people's mandate and hence the right to conduct such important trials.
