The Constitution only says defense, it says nothing about wars of choice or spending as much on the military as the rest of the world combined. I have no problem cutting waste wherever it is in the government.
What waste besides the excessive military do you see needs to be made. Despite the GOP complaining about spending, they continue to spend as much as the rest of the world combined on the military and have not offered any specific cuts they want made.
Ok, you seem to think Afghanistan was unnecessary, since you seem to believe that, perhaps you could tell all of us what exactly we should of done after being attacked? The Afghans weren't going to turn anyone over to us nor stop them having training bases and secure facilities. What do you think were our other options?
Lets see, although I don't particularly like SS or Medicare, they are at least separate deductions and are supposed be separated from the general budget. But other things, I said them before, Welfare, Medicaid, HUD, Support of the Arts, Support of PBS (basically support of any such programs that do not have to do with basic governmental responsibilities), BATF (and other redundant Law Enforcement at the federal level), Federally funded unemployment, any program that exists simply to create jobs, About half of the education budget (force better management, reduce wastage and get rid of unneeded programs), not just Welfare, but pretty much all of health and human services, all funding for disease research, reduce and reorganize EPA, all investment into research that is not directly related to the military (and NASA, as they play a significant role in military capabilities.), replace all contractors with direct hire and direct manufacture of government specific needed equipment, Blackwater and other such firms and return those security functions back to the military, a lot of FEMA, realign and bring the CIA, homeland security and other "intelligence" agency into a single agency, stop all DOJ lawsuits against states, remove and eliminate multiple levels of redundancy in management of all government function, make Congress use public transportation instead of government owned ones, switch Congress to the Tri-Care Healthcare program mandated for the military, end retirement pay for Congressmen and Senators who do not serve at least 20 years, convert a large portion of VA over to an improved Tri-Care/private insurance policy system to meet their needs and provided, free of charge, to all retirees and disabled veterans and their dependents, convert 95% of Pilot slots in the Navy and Air Force to Warrant Officers instead of commissioned officers, greatly reduce the Officer Corp back to ratios of Officers to Enlisted levels at least as low as during Vietnam, possible as far as WWII, make the military budget a general budget and let the services decide how to spend it, not Congress, but of course keep oversight, reduce the budget for Congressional operations (Basically get rid of a lot of pages and interns(if they are paid)), reduce the operating budget for the White House, other than security, make all Congressional and Presidential vacations be paid for by those taking the Vacation, make funded and organized lobbying illegal, end all "Pork Barrel" funding, make Human Right (other than death penalty), Freedom of Religion and open markets a requirement before providing foreign aid, reorganize and consolidate overseas bases, end Affirmative Action, end requirement to contract with minority owned companies, stop all funding provided to institutions who use race or sex as a selection criteria, convert all prisons into self-sustaining farms/factories (any sale of goods will be at average market price and will not undercut private enterprise). Probably more if I looked at things closely.
Things I would do to improve the economy and improve tax revenue-- flat tax across the board for everyone, use workfare participants to do a lot of work we now pay others, especially contractors, to do, end all Free Trade agreements with countries that do not have economies capable of buying a significant amount of our products, end the practice of reducing or eliminating tariffs for companies who build in the US, extending Tariff reduction to only those products produced in the US, Create an office of Patents which will hold all patents produced or paid for by federal funding and collect fees for licensing of those patents, allow the government to hold stocks of private companies as long as it is not a controlling interest, the stocks historically pay dividends, the company is not currently in financial difficulties and investment is kept equal amongst competing publicly held companies, create an agency dedicated to investing/making loans to inventors so they don't have to sell them to existing companies and can enter the competitive market, also for small business investment/loans, completely redo the education system, introducing multi-path options made either by choice and/or by capabilities, including skills training, so that graduates actually graduate high school and will be able to get something other than low-wage non career jobs, invest into or at least make loans to build Nuclear plants and other large scale electrical energy producing plants to replace all fossil fuel plants, institute a graduated tax system based upon percentage of profit for business, introduce a moderately high tax for all rail that does not convert to electric rail and increase it every five years until all rail is electric, replan and rebuild public transportation net works to be only electric based and is focused on efficiently moving workers from home to work and home to shopping centers, I'm tired of typing, not out of suggestions.
