It's a shame some people are willfully misunderstanding the OP's question and in doing so are ignoring the very real risks of a much wider conflict which could end very badly for Israel.
If this dispute was contained between Israel and Hamas then of course it would be no contest, a US supported Israel would win in the end. The win would be relatively short term because Israel's current actions will become a recruitment tool for extremist organisations.
I am listening to what is being said in the UN Security Council meetings, political leaders in the region, experienced military people and intelligence analysts.
Most of the Muslim/Arab world have called for a cease fire and humanitarian aid to be allowed to enter Gaza. Other countries in the region have called for a diplomatic/political resolution but Israel shows no signs of listening. Now we have Egypt and Jordan calling out the west for its hypocrisy. Multiple armed militia groups/Iranian proxies in Lebanon, Syria, Iraq and Yemen, Iran is making direct threats and has the military power to follow through. Erdogan is losing patience and Pakistani have said if Turkey needs nukes they will supply. Turkey is the biggest military in the region and can almost match the US in terms of numbers of military personnel and has an additional 325k reservists. China and Russia are pissed off and have deployed military assets in the region.
Add on top of this that wherever the US and allies have intervened we leave behind countries in ruin with barely functioning government. I think the ME is fed up of our regime change/war on terror/peace keeping endeavours.
If those countries decide to become involved and provide coordinated support for each other then there will be little Israel, the US and it's allies can do to repel them.
I can't answer the OP's question but if our political leaders continue to ignore the risks and encourage Israel then I think Israel may regret it's destroy Hamas at ALL costs approach. The people of Israel deserve better.
