This is going a very tricky decision for the ICC.
You can't really use the current world rankings because ranking points will be won or lost against teams that are not eligible for the Olympics.
I think that any country who fails to qualify because will launch an appeal to the Court of Arbitration for Sport and probably win.
So here's what I suggest for the six.
1 Possible host country place - USA - but only possible - what you do is recalculate the ICC rankings and take out all points gained against non-Olympic teams.
Then once you done this and taken out non-Olympic countries like West Indies and either England and Scotland then if the USA are in a high enough ranking position they qualify. This position could be as high as 10th or as low as 20th depending on how important the IOC and ICC see their presence in LA.
(I'm assuming that, like in curling and women's soccer Great Britain would nominate either England or Scotland as their official qualifying representatives)
USA are currently 18th
2 2026 World T20 champions
3 and 4 Asia-Pacific qualifying tournament winners and runners-up
5 and 6 Euro-Africa-Americas qualifying tournament winners and runners-up
(7) If the USA don't meet the qualifying standard then a play off between the 3rd place teams in the 2 above categories decides the final qualifiers
The qualifying tournament would be held under IOC eligibility rules not the ICC rules
