I think a war involved in landing troops into Taiwan is a bad idea. If I am in charge, I would just bomb every military installations, presidential palace, all bunker and hideouts, and schools and call it a day. That is how the israel won the war. Most gaza and Lebanon leaders are dead without even stepping foot on the enemy's territory.
On the other hand, if the enemy is demoralized and doesn't want to fight, you can march in with 300 troops and take over without a single shot fired, see Syria and Afghanistan.
Note that Israel still does not control Lebanon or Gaza, but the Syrian rebels do control Syria and the Taliban does control Afghanistan. You can't acquire and hold territory without troops on the ground.
