Who asked you for a full scale war when many things are settled in border conflicts or the possibility of a border conflict? Please, read more war histories. They are not always WW, regional wars, bilateral full-fledged wars. Most are border wars.You would have bd destroy it's progress and infrastructure in a full scale war and for only world powers to exploit the situation. Similar scenarios played in Africa and look how Africa panned out.

Since BD leadership was unwilling to challenge MM, the latter forced its will on it. BD's Hasina lacks motivation to challenges its neighbors. In previous times things were different and MM backed down. One was in 2001 when Khaleda was the PM. MM Backed down from the Naf River spur building. The 2nd time was in 2008 when General Moin was leading the country. MM Navy backed out of contested BoB water.
They had spines and Hasina has none. MM did not do such things without knowing the weak psychology of Hasina and used it to insult BD without firing a bullet. Many wars are fought without bullets but with psychological and diplomatic strengths. Hasina is a failure.
