You wait long long.
No ransom will be paid.
Even if NYK decides to pay that $1 billion, because:-
a) Humanity had decided collectively to NEVER meet terrorists demands. Even if NYK paid, it will have to recoup that billion dollars back & it is by CHARGING HIGHER RATES for logistic services, & eventually, it will only price itself out of competition & go bankrupt, with hundred thousands of its employees left unemployed
b)Hizbollah WILL only demand more & more for each ship that passes thru the gulf of Aden
