I'm in the year 190 BC, just send an expeditioanry force to Greek and manage to conquer one of the 7 wonders. Now the people are begging me to march to Rome and overthrow the Senate ? Is it the right time ?

I do have large armies but but my Julii legions are spread all over europe and the british isles. (I've conquered Gaul, Britons and Spanish while Germans are under my protectorate.) I'm building a large high tech army in Italy but they are all 'green' unit (no war experience).

If I draw all my forces back from far flung region, it will open up for rebellion. Shall I wait the builup further ? Or will other faction atack me first ?
