i'll have to disappoint you there, the story in question has been removed entirely... it was either on webnovel.com or royalroad but i can't find it on either, so it's probably gone for good. well, you are not losing out on much, the story had only a handful chapters and the english was very bad. since i wrote that original comment i have seen a few other stories that seem to have promise, at least from the synopsis. just search for defense or tower defense and skim through the short lists. i can't give you any recommendations though, my story taste has moved to other themes since then.

better presidential choices? i don't know if that is really the case. i'd say we are about even in the bad choices available. the american choices are better than child molesters, true, but at least from what i heard there are some borderline criminal stuff happening from or around them. (trump in particular) as for europe, yeah, some countries have some pretty bad leaders, though some others are ok. i can't tell you which countries are good in that regard though, since i have very little interest in politics and only the bad stuff actually gets into the news. i mean, if a president makes election promises and actually keeps them, nobody will really notice. ...hm, yeah, that is something people should care more about, in my opinion. election promises should matter more. in my opinion leaders should not lie to the people why are about to rule just to get to the position easier. i suggest a system where any president or station close to power has to keep their election promises or pay a hefty fine. something like 50% of their total savings in all forms and at the least several millions total. the weight of their responsibilities as the leaders of millions should have ... 'downsides' too, for lack of a better word.

wether america is better than europe or not is a matter of perspective. i, as a european, would argue that a country where everyone can easily get firearms and where thousands of people are shot to death each year sounds areful. while americans see no problem with that or even actively support it. and americans surely think about europe similarly bad. i mean, we have been in the center of both world wars, we have a whole bunch of different cultures and languages and use somewhat different governmental systems. there is a lot we can both disagree on.

20 football fields? americans really use whatever they can to avoid the metric system...

4hell? why the 4?

no, every city has a wall by default. and that wall is definitely higher than a person. so there is now a tower within the city, unable to see or shoot any ground targets... well, at least that tower will not really be relevant at all. he get much better stuff at a rapid pace.

it can still affect big objects even a billion lightyears away? dude, the whole milkyway galaxy is only 52.850 lightyears big! if the super lagre blackholes had that much attraction power, the whole local group would have collapsed in on each other long ago. not to mention that the stars in the galaxies would have either been sucked into the center blackhole or would have way bigger galactic orbits. both is not the case. and also no, neptune is not 100+AU away from the sun, its closer to 30AU. at least according to google. and our sun alone is already not as attractive as you think. we can already make objects that can travel beyond the scope of our suns gravity well. i'm talking about the voyager probes. they will even make it beyond the galactic gravity well in a few thousand years, if they survive till then of course. and another misconception you seem to have, heavier objects don't pull stronger then swarms of smaller objects with the same collective weight/mass. each particle with mass pulls on each other object with mass in the whole universe. it's just that big heavy things have a lot of those particles in one place, so the pull is more focussed towards that direction. if heavy objects pull that much harder on lighter objects, like you say, than light would be attracted beyond escape from even just little pebbles, because light is just that lightweight. (pun not intended) so you say i seriously underestimate gravity? i say it is you that clearly overestimates gravity. but if you find prove that i'm wrong, i'll happily admit it. i'm not perfect or all-knowing after all.
