well i'm not really any good at scripting, but if you want them to attack you via the sea route sometimes opening descr_sm_factions and then changing 'preferes_naval_invasion no' to 'yes' sometimes makes the AI use their ships to transport armies more and you could have a better war on your hands... i've done this to the scipii and they actually expand beyond sicily which is good
but if you just wanted a ceasefire via script i am not really good at scripting so wait til some scripter comes on to explain it cos i just can't
