Arms control:

58彩票US President Donald Trump: The Trump administration has withdrawn the United States from the 2015 Iran nuclear deal, the 1987 Intermediate Range Nuclear Forces Treaty, and (almost) the 1992 Open Skies Treaty. Due to concerns about China's defense relations in the Middle East, it has relaxed restrictions on the sale of armed drones to foreign governments under the missile technology control regime. As of the time of press, government officials have been unwilling to extend the 2010 New START nuclear agreement with Russia, which is set to expire in February, and insist that the new version includes Russia's growing tactical nuclear arsenal and China's rapidly expanding small arms arsenal, seemingly unwilling to sign such an agreement.

Former US Vice President Biden: favored by arms control advocates, Biden has promised to renew New START and may accept Russia's unconditional five-year extension proposal. He also said that if the Iran nuclear agreement is restored to a fully compliant state as stated in the agreement, he will rejoin the Iran nuclear agreement. Although Trump has relaxed restrictions on the use of landmines by the US military in conflict areas, Biden has stated that this move unnecessarily puts civilians in danger and he will reverse the situation.

nuclear weapon:

58彩票Trump: It is expected that the current president will continue to modernize all three branches of the nuclear arsenal, despite increasing budget pressures, with bipartisan support in Congress. Trump deployed the W76-2 submarine launched low yield nuclear warhead to counter similar Russian weapons, and he also plans to build submarine launched cruise missiles or SLCMs. Trump approved a nuclear weapons budget request of $44.5 billion in fiscal year 2021, an increase of approximately 19%, intended for the W76-2, some ongoing nuclear warhead life extension programs, future W93 submarine launched ballistic missile warheads, and the production of at least 80 P-pits annually for nuclear warheads.

Biden: Biden hinted that he will reduce Trump's rallies. The Democratic presidential candidate opposes W76-2 and SLCM. Biden will face pressure from the left to abandon plans to build a new intercontinental ballistic missile nuclear force to replace the 1970 Minuteman III fleet, although he has not yet announced his position. Biden said he will review a policy that retains the option to use nuclear weapons first.

Defense budget:

Trump: The Pentagon's five-year defense plan indicates that it will require defense spending to remain unchanged after 2021, and under pressure from coronavirus related spending, it is widely expected that the budget will remain unchanged, regardless of who the president is. Trump set records for the highest total defense revenue in 2018, with $700 billion, $716 billion in 2019, and $733 billion in 2020, as he established the new Space Force. He also misappropriated billions of dollars in defense funds to fund the southern border wall and supported a proposal for a $750 billion defense budget in 2018, calling it "crazy".

58彩票Biden: Biden said that Trump has "abandoned all fiscal discipline on defense spending," and although he expects the United States to significantly reduce defense spending if elected, he will face pressure from the left to cut spending. Biden said that in order to contain Russia and China at an affordable cost, he will shift investment from "legacy systems unrelated to them" to "intelligent investments in technology and innovation, including in the fields of networks, space, unmanned systems, and artificial intelligence. He also hopes to promote neglected non military investments, such as "diplomacy, economic power, education, and technology

Afghanistan, Iraq, and Iran:

Trump: Both candidates denounced the 'endless war' and vowed to bring American troops home from Afghanistan. After peace talks with the Taliban, the United States reduced its troops to 8600 in June and plans to reach 4500 by November, with no further presence in the spring. For Iraq, Trump plans to increase the number from 5200 to 3000 by November. On the issue of Iran, Trump withdrew from the US nuclear agreement and re imposed destructive trade sanctions as part of the maximum pressure action. The US government recently warned its allies that it may target leaders of Iranian backed militia groups that target the US military and diplomatic missions in Iran.

Biden: Biden vows to bring back US combat troops from Iraq and Afghanistan, which may leave behind residual anti-terrorism forces. His camp prefers small-scale operations (possibly led by special forces) rather than large-scale and unlimited force deployment. He agrees that this requires the informed consent of the American people. Biden voted for the Iraq War while serving as a senator, and in his current campaign, he said he played a key role in the Obama administration's withdrawal of 150000 troops from Iraq. On the issue of Iran, he said he will be committed to preventing the country from acquiring nuclear weapons, providing a diplomatic pathway while maintaining targeted sanctions, and working closely with Israel to ensure that this US ally can defend against Iran and its proxies.
