You are precise in respect of BAL's initial plan, Idune----nevertheless, snugglepot also appear to be correct in summing up the current scenario. In fact:
1. Initial Plan of BAL (due to which she deeply fell for 'the lefts')---as you said---was to re-use (mass sentiment again & again) centering WC Trial but more to hit the additional 'bigger' target (as coaxed by 'lefts') was to ban Islamic politics JI and all), institution, businesses, orgs.
2. Jolted by the "gr-grr" of Ulema lions, and finding suddenly that BAL itself caught in a trap, she has backed out from banning Islamic parties & others---even JI. Now her stance is that BAL will not ban any one on its own unless ordered by the court. She wants none to speak on this issue, at all (and 'bum' and 'Shahbagi's are fuming to see miss the 'prey' and and to watch closely how Ulemas will re-act if BAL gag only JI, and whether BNP & JI will be able to arouse Ulemas again even to higher temperatire' on that issue. BAL suddenly realized that their image of a pro-islamic party which painstakingly was built by SH performing haj and then traveling all places with hijab on head and beads at hand is growingly dis-appearing. Now maybe hundred hajjs will not be adequate. Patronizing Shahbagis and applying excessive force & killing more than 2 dozens, now BAL is potrayed as "Patrons of Atheists"----too deadly-lethal for a mass-oriented vote-seeking political party. Currently, Govt is too worried: "Lefts" and "Shahbagis ', too realized BAL's deception (1) It can not (because of 'Judicial' procedures / International Watch-dogs hang any one like that nor in a position to afford "banning" JI ? Islamic politics (as demaded by the 'master' using executive power---because of the risks from Ulema (and BNP JI) potential combination in any event as mistrust is rampant---furher complicated by Mahmudur. It is very likely that Shabagis and "Lefts" will become a big laibility on BAL soon---more public ramifications are likely which may be triggered by recent ToI news. (Headline in 'amardesh' and 1st page in 'Naya Diganta'). Mass will swallow this piece without salt & water---as many had been suspecting such from many obvios indications. Sorrily, BAL & SH are trapped in the same hole dug by them. (2) Ulema will cotinuously push BAL to route-out and 'dis-own' Shahbagis' as they are not trusted by Ulemas as one may do for the snakes, and also not to arrest Mahmudur, and may errupt again / any time in the process. Awaitings in cue are 'What BNP does with mass-related real-life issues, Padma Bridge (after Canadian Court takes up the case in April, and discloses few names) etc. etc. Another long-brewing issue is 'Not forgottent' 'Not forgeven' 25th February---in the spitit of '71.
3.But, snugglepot is expecting an "all party' meeting will ease-out / remove the mess. What many are apprehending, that further mistakes BAL and its obstinacy / not aggreeing to CTG---may incite further highly-flammable mistakes. JI is a 'cornered' cat now---proverb says that it may now go for the jugular. So, all players now need 'cool' & 'level' heads. BNP should play an ideal 'balanced' role now as a saner player, and show how it is better than BAL. Or, is it really?
