I believe that Bernie shall say more than "it's immoral that United States in the only major country that doesn't have X". Take the healthcare issue for example. He shall also say that our health care system is too expensive thanks to medical industrial complex (he can make a Breaking Bad joke here, our chemistry teachers has to sell crystal meth to pay their hospital bills etc). If we have single payer system now, we would be saving about a trillion dollar every year and for 95% of Americans healthcare would be cheaper and our budget will be balanced. After all, Obamacare doesn't address the core problems of our broken healthcare system

And foreign policy Many criticize Bernie Sanders for lack of foreign policy experience. I also believe that he shall say more than "I voted against Iraq War" Main premise US military is now trying to prepared to be engaged in four fronts. Urban warfare in deserts of Middle East, guerrilla warfare in mountains of Afghanistan, armored warfare in Eastern Europe and air-sea battles in Asia Pacific region. These are completely different settings, requiring different training and different equipment. And it's not sustainable US shall partly disengage from Middle East. Set 4-5 red lines such as Suez Channel, Hormuz Strait, Another Arab-Israel War, Nuclear weapons etc and unless those red lines are breached, we shall not engage in military conflicts in Middle East. However we shall focus on Asia-Pacific region and Africa, that's where the future is. Here's my advises 1) Talk about how Libyan War is similar to Iraq War. Now Libya has two capitals and two governments. One in Tobruk, other one is in Tripoli. Thousand people are killed, many flee in Europe. Armory of Ghaddafi was looted. 15,000 MANPADS (Should fired Surface to Air Missiles capable of shooting low flying commercial aircraft) are missing, so as anti-tank missiles. I think American people deserve more than this "shoot first ask questions later" foreign policy. We need a foreign policy vision who thinks not only today but also tomorrow. Hillary would probably say "Are you implying Libya was safer with Ghaddafi?" or something like that. Bernie shall response "We heard similar rhetoric from Rumsfeld and Chaney about Iraq. One of the reasons for I voted against Iraq War because they do not have post-invasion plan, they foolishly believe that we would be welcomed as liberators. Unfortunately, both Republicans and some establishment democrats believe that whenever we bomb a Muslim country, a pro-Western democratic society emerge and we will be seeing gay prides in Tripoli or in Baghdad in 6 months". 2) On Syria Bernie shall say "Both Secretary Clinton and I am old enough to remember how US entered Vietnam War. It also started "let's send some special forces, let's send some trainers and it goes on and goes on. I fear that Syria could be the next Vietnam. Everyone is talking about how much soldiers we shall send to Syria. however no one talks about what are we trying to accomplish in Syria because there is no answer. We say we don't want ISIS, we don't want Assad, we don't want other radical islamist groups. Then who's left. Yes, ISIS is a disgrace to humanity but American people shall not be the only nation to risk its soldiers lives and its taxpayers money. 3) On Afghanistan We went to Afghanistan to get Bin Laden. Now Bin Laden is dead (Praise Obama here). So WTF are we doing in Afghanistan. Bring our boys back. Also criticize drone policy. Our drone policy is acting like a SuperPAC for Taliban. In order to take out a bad guy, we kill 10 civilians including women and children. If Afghan government wants, we can provide airstrikes against Taliban. 4) On Ukraine Bernie shall say "We have to give a response to Putin in Ukraine". According to 1994 Budapest agreement, US is promised (although it is not as bounding as NATO Treaty Article 5) to protect Ukraine. Ukraine has a pro-West government and they do not have heavy arms against pro-Russia rebels. With the help of NATO allies, we should send heavy arms to Ukraine and maybe some advisers and help them to take Eastern Ukraine back. Then we shall negotiate Putin for Crimea. If Russia refused to negotiate and/or doesn't give back Crimea, we shall impose further sanctions, militarization of Eastern Europe (Putting more anti-missile systems, more NATO exercises etc) Maybe he shall also add..we must courage Europeans to spend more on military. 5) Against China Praise Obama for its pivot to Asia. We shall stand for our allies such as Japan, South Korea, Philippines and Vietnam against a more aggressive China. 5) In Africa Africa is next-Pacific region and Chinese are doing a great job here. What Chinese do is that instead of traditional "here is some cash, so give me your mines", they say "give me your mines and I will built roads, dams, hospitals, stadiums for your country". So they win people's hearts. US shall also follow a similar path.
